ATLAS
The ATLAS experiment at the Large Hadron Collider (LHC) at CERN, Geneva, is a multi-purpose experiment for particle physics, run by an international collaboration of 3000 physicists from 182 labs and universities representing 38 countries world-wide.
ATLAS started taking data in 2009, and will continue to do so till 2035. The experiment has discovered in 2012 the Higgs boson which provides a mass to all the elementary particles, and since then is scrutinizing its properties. The collaboration is also looking for new particles beyond the current theoretical framework, that could for instance explain the dark matter in the universe.
The ATLAS team at CPPM gathers about 45 physicists, engineers, PhD students and post-doctoral fellows. The team has been a member of the ATLAS collaboration since its inception in 1994.
We took part in the design, construction, testing and implementation of several elements of the ATLAS detector: the pixel detector (front-end electronics and mechanics, assembly, cooling), the electromagnetic calorimeter (project manager for the end-caps),the triggering system (high level architecture).
Building on this expertise, we are deeply involved in the performance studies including the identification of jets from /bottom/ quarks and of electrons. Our physics program in Run 2 follows two axes exploiting these signatures: new physics searches, in particular supersymmetry, and the study of the properties of Higgs boson and notably its coupling to the /top/ quark.
Ahead of Run 3 (and beyond), the team contributes to the upgrade program of the electronics for the electromagnetic calorimeter trigger. The team is also actively involved in the pixel R&D (electronics, mechanics, simulations) for the new ITK tracker for the high-luminosity phase of LHC.

June the 2nd, 2022 : Georges Aad, researcher in the CPPMATLAS team, has received an « Outstanding Achievement Award 2022 », a prize given by the ATLAS collaboration for «exceptional contribution to the digital electronic system of the ATLAS Liquid Argon calorimeter trigger», a phase 1 upgrade installed and starting operation for the LHC Run 3, to efficiently treat increased event pile-up related to the higher luminosity of LHC. This prize acknowledges and rewards the importance and the quality of the CPPM ATLAS team work in this project. The finalization of this upgrade is on-going and the CPPM, with engineers, students and physicists is responsible for several key aspects. The new system is operational and collects the first collision data that the LHC has just started producing on May 28th, 2022 as Run 3 is now starting.
-
April 18th, 2022 : To prepare the production phase of the future ATLAS pixel detector for HL-LHC (ITK Pixel Detector project), the « mechanics and production » team has developed an automated glue deposition method, for the cells that shelter the modules before integration in the mechanical structures of the detector. This highly reliable method allows to deposit a quantity of glue with a 4% accuracy for 400 mg of glue used. This is important in order not to degrade the detector’s performance and guaranty a lifetime above 10 years in-situ. The production phase for the detector will take place from 2024 to 2026 and our team will handle the integration of about 50 modules per month during this phase.
-
March, 2022 : The ATLAS and CMS Collaborations have released as an input for the US Snowmass prospective exercise a common White Paper summarizing the most recent physics projection results for the High-Luminosity phase of the LHC (HL-LHC). The CPPM group was in particular directly involved in the prospect result related to the search for di-Higgs production at HL-LHC, which is one of the main cornerstones of the ATLAS HL-LHC physics program. Those results have confirmed that a 3-sigma evidence with ATLAS data and a 5-sigma observation combining with CMS is definitely by the end of HL-LHC data-taking.
-
December 13th-16th, 2021 : 13th FCPPL “France-China Particle Physics laboratory” workshop, in which the group was represented with presentations giving status reports of activities in the framework of several collaborations between our team and partner teams in China.
-
November 22nd, 2021 : The CPPM ATLAS team has been involved for many years in the search, the observation, and then the study of the Higgs boson production with a top quark pair. The ATLAS collaboration has just published a new study in which the Higgs boson decays to a b quark pair. The Higgs field gives mass to elementary particles by means of its interaction. The very heavy mass of the top quark (almost as heavy as a gold atom!) hints to the top quark having a special relation to the Higgs, and the study of this relation is the topic of these analyses. For the first time in this channel, the analysis is performed as a function of the Higgs boson transverse momentum. The CPPM team has deeply contributed to this study, in particular with the development of machine learning techniques.
-
November 2021 : Beam circulation has started in the LHC at the injection energy (2x450 GeV) in stable mode. The ATLAS detector registers new data and in particular with its Liquid Argon (LAr) Calorimeter. The LAr calorimeter has seen a major update during the recent long shutdown, for which the CPPM team was extremely active. The LAr system has started transmitting data for the first time with its new updated readout system and in particular in direction of the calorimeter first level trigger. This is an important milestone towards Run 3, which starts in spring 2022.
-
October 21st 2021 : Publication of the ECFA document(European Committee for Future Accelerators) concerning detector R&D perspectives and organization « Detector Research and Development Roadmap ». This document will structure detector R&D at colliders for the years to come.
-
End of October, 2021 : Protons are back in the LHC ! After more than two years of maintenance and updating of the collider and the detectors, LHC pilot runs are currently ongoing. The ATLAS detector recorded “Splash” events (a flux of particles resulting from the interaction between the beams and a collimator located before the detector). The first proton frictions happened at the LHC injection energy (450 GeV per beam) in stable mode in the last week of October. This has allowed ATLAS to register these first data and to validate its good functioning. In June 2022 this will be the start of Run 3, for which the LHC will raise its center of mass energy from 13 to 13.6 TeV.
-
June 2021 : Publication on the configuration and the performances of the Run 2 b-jet trigger. The Run 2 High Level Trigger (HLT) reduces the data rate from 100 kHz at the level 1 trigger output to save events on disk at a rate of about 1 kHz. The hadronic jets containing b-quarks are identified (b-tagged) in the HLT by exploiting the properties of b-hadrons, which have a relatively long lifetime, of the order of 1.5 ps, to reconstruct secondary vertices typically located few mm away from the hard-scatter interaction. The b-jet trigger software was redesigned to improve stability under increasingly harsh pile-up conditions. These changes, together with improved tracking performance in the trigger, the installation of the insertable B-layer for Run 2, and the usage of the most advanced algorithms lead to significantly improved performance compared to Run 1. The CPPM group has contributed to the success of the Run 2 b-jet trigger with multiples responsibilities (monitoring, software development and validation, calibration).
-
February 2021 : Probing for Single Event Effects (SEE) at the GANIL accelerator. The structures that were tested are memory blocks conceived to be SEE-resistant. They use hardening methods such as data and control line redundancy, memory triplication, DICE cells, physical layout level separation…. The tested memories are implemented in three different technologies (TJ180, AMS180 and LF150). This work is done in the framework of the DICE master project and of the RD50 collaboration.
-
End march 2021 : The ATLAS collaboration has released a new result on the Higgs boson self-interaction, looking for events containing a Higgs boson pair. This process is very rare, about 1000 times rarer than the production of a Higgs boson alone. Events where one Higgs boson decays to two photons and the other Higgs bosons to two bottom quarks are a powerful handle to search for Higgs boson pair production. New analysis technics were developed to search for this rare process (only 12 such events would have been produced at the LHC so far) by several teams, including the ATLAS team of CPPM. Limits were set on how often pairs of Higgs bosons are produced, at 4.1 times the Standard Model prediction. This result sets the world's best limits on the Higgs self-coupling. But we will need much more data to precisely measure the Higgs self-coupling and to see whether it agrees with the Standard Model prediction. The High-Luminosity upgrade of the LHC plans to deliver a dataset 20 times larger than the one we used for this study. The ATLAS group at CPPM is deeply involved in the upgrade of the detectors for this new phase.

End of March 2020: While the virus’ proliferation is spreading rapidly in different parts of the world, the researchers mobilize international action in response to the new coronavirus. The grid computing infrastructure at CPPM that is mainly used during normal time by the LHC experiments ATLAS and LHCb in the context of WLCG collaboration (Worldwide LHC Computing Grid) is now ready to receive more jobs from biomedical research projects related to Covid-19 research studies. We work in coordination with the virtual organisation biomed and INSERM computing for researchers to have access to our ressources.

March, 30th 2020: The CPPM grid computing infrastructure for ATLAS is now considered as a Nucleus. The Nucleus sites are the main processing sites receiving data directly staged at CC-IN2P3 (Tier-1) but processed outside CC-IN2P3. To have this Tier-1 like status, the grid site needs to have enough storage, very good availability and processing efficiency for data in addition to a good network bandwidth. So far, only the LAPP Tier-2 had this status in France. It is therefore a recognition for the CPPM Tier 2.

March, 17th 2020: On March 17 2020, the ITkPixV1 chip was submitted to the TSMC foundry for production. With a surface area of more than 4 cm², this chip has been designed in the 65 nm CMOS process and will tolerate an ionizing dose of more than 500 Mrad. It contains more than 1/2 billion transistors and 153600 pixels of 50x50 µm² organized in 2400 regions of 8x8 pixels. This is the culmination of nearly 8 years of work by CERN's RD53 collaboration, to which the CPPM's ATLAS team has been a major contributor since its foundation. This is the pre-production version of the chip which will equip, in more than 33,000 units, the 5 internal pixel layers of the future ATLAS post-2026 trajectograph. This is a major step towards improving the ATLAS detector for the High Luminosity phase of CERN's Large Hadron Collider, which has now been completed.

Belle II
The Belle II experiment is installed at the e+e- SuperKEKB accelarator in Japan. Its goal is to study the properties of beauty and charmed mesons as well as tau leptons, as a way to search for physics beyond the Standard Model.
The physics data taking with a complete detector started in spring 2019 with the final goal to collect a dataset 50 times bigger than the previous experiment, Belle.
The collaboration has more than 1000 members. France participates through three laboratories: LAL, IPHC and CPPM.
The interests of CPPM are focused on data analysis involving tau leptons: tau lepton flavor violating decays and rare decays of B to tau. These activities are developed thanks to European fundings obtained by Justine Serrano (ERC consolidator grant ’NEPAL’)

March 2023: New Belle II results presented at Moriond 2023
The Belle II experiment presented 14 new results at the Moriond conference, among which two were obtained by the CPPM team:
- The measurement of the B->D(*)KKs branching fractions, with a precision improved by a factor 3 for the B- -> D0K0Ks decays and three new decay modes observed. This will allow to improve the simulation and B tagging algorithm. This result was presented by Valerio Bertacchi, post doc at CPPM.
- The search for the lepton flavour violating decays tau -> ephi and tau ->muphi. This analysis was the subject of Leonard Polat's PhD and was presented by Laura Zani, former post doc of the CPPM team. The statistic used (190 fb-1) does not yet allow to improve the existing limits but this will possibly be achieved with the 424 fb-1 already recorded before the long shutdown.
May 2022:
Organisation of the Belle II face to face tracking workshop, 11-13 May.
October 2021:
Laura Zani has been awarded the first annual Belle II thesis prize, together with Giacomo De Pietro, for her thesis: "Search for an invisible Z’ in μ⁺μ⁻ plus missing energy events at Belle II” (thesis submitted to University of Pisa).
March 2021:
Organisation of first Belle II Masterclass at CPPM.
June 2020:
SuperKEKB reached a peak luminosiy of 2.226 x cm s , breaking the world record!
March 2020:
The Belle II international collaboration has published its first results in a paper selected as an Editors’ Suggestion in Physical Review Letters The paper reports the first search for a new type of elementary particle that may act as a “portal” between ordinary matter and dark matter, which is understood to make up some 85% of the matter in the universe.
This search has been the thesis work of Laura Zani, who recently joined the CPPM group.
Dark Matter
Dark matter is today one of the main puzzles in fundamental physics. Indeed, its contribution to the total mass of the Universe is 85%, but it can not be explained in the framework of the Standard Model of particle physics. However several candidates exist in theories beyond the Standard Model, amongst which the WIMP (Weakly Interactive Massive Particle) and the axion are two better-motivated candidates than most others. In this context, the CPPM Dark Matter team is deeply involved in the following experiments:
- DarkSide-20k: second generation experiment for WIMP direct searches. Located 1.4 km underground in the Gran Sasso laboratory in Italy, it is in a prototyping phase and aims to start physics data taking by 2026.
- MadMax: first generation experiment for axion direct searches, based on a novel concept (dielectric haloscope). It is in an innovative and challenging R&D phase, with different prototypes being tested under magnetic field at CERN between 2022 and 2025.
They both have a strong discovery potential in the next ten years.

Since 2010, the most sensitive technology for WIMP direct searches is based on the measurement of the scintillation light from the scattering of a WIMP on a liquid noble atom – argon or xenon. The DarkSide-20k experiment, located 1.4 km underground in the Gran Sasso laboratory in Italy, is the second generation of liquid argon dual phase Time Projection Chambers (TPC). It is in a prototyping phase and aims to start physics data taking by 2026. It will use 50 tons of highly purified argon, allowing a world leading discovery potential for WIMPs. It will be the largest TPC ever built for dark matter searches and a dedicated effort to calibrate its response is obviously a key element of its physics program. To this end, the guide tube system that CPPM will design, build and install at Gran Sasso laboratory will enable the circulation of photon and neutron sources around the DarkSide-20k TPC. We also participate to radon diffusion measurements and data analysis of the prototype.
MadMax is a first generation experiment for axion direct searches, based on a novel concept (dielectric haloscope). It is the only one capable to explore the axion mass phase space between 40 and 400 eV, favored by the theory. Currently in an R&D phase, it will take data with different prototypes between 2022 and 2025, and with the final detector after 2028, with a strong discovery potential. In CPPM, we exploit our recognized expertise in 3-dimensional measurements with micro-meter precision, largely developed for ATLAS pixel detectors. We thus precisely measure the geometry of the dielectric disks, which has to be controlled at the micron level. We are also responsible for the design of the ring structure to hold the disks. Finally, we are responsible for all infrastructures at CERN that are needed to take data with the prototype inside a magnetic field.

LHCb
The LHCb experiment is installed at the LHC, the Large Hadron Collider, at CERN, in Geneva.
The purpose of the experiment is to uncover New Physics by performing precision measurements in the decays of beauty and charm hadrons.
The LHCb collaboration has 1380 members from 79 laboratories and
universities in 18 countries.
At CPPM, the team designed the muon trigger system for Run1&2 and the 40MHz acquisition boards for Run3 and beyond. We ensure the coordination of the DIRAC project which constitutes the basis of the distributed computing system.
We have played a major role in several key analyses ( , ) and are currently focusing our efforts on some of the modes related to "flavor anomalies" (neutral and charged) observed by the LHCb, Belle and BaBar experiments, the combined effects of which show a deviation of about from the theoretical predictions. We are specifically studying the rare modes with in the final state, , and the ratio between the branching ratios .
