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.

  • 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.

  • February 2021 : Emmanuel Monnier has been re-elected as ATLAS Liquid Argon Calorimeter Project Leader for two years, with his new terms starting on March 1st 2021.

  • October, 29th 2020 : New results concerning the production of the Higgs boson in association to a top quark pair (ttH) were shown at the Higgs 2020 conference. This analysis concerns the complete ATLAS Run 2 set (139 fb-1) and benefited from the strong work from several members of our group.

  • October, 8th 2020: Submission to the European Physical Journal C of the paper "Search for phenomena beyond the Standard Model in events with large b-jet multiplicity using the ATLAS detector at the LHC". This analysis, to which our group is a strong contributor, allows to establish model-independent limits to the presence of new physics in events with high b-jet multiplicity and, at the same time, to constrain natural supersymmetric models violating the R-Parity.

  • 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.

  • January 2020: The CERN Yellow Report "Physics of the HL-LHC, and perspectives at the HE-LHC" is now published. This report summarizes the outcome of five working groups that have studied the physics potential of the High-Luminosity phase of the LHC (14 TeV HL-LHC) as well as perspectives for a future possible High Energy LHC (27 TeV HE-LHC), and covers topics such as: Standard Model measurements, Higgs boson properties, flavor physics with heavy quarks, QCD at high density and temperature, and searches for phenomena Beyond the Standard Model. The ~1400 pages report can be found at CERN Yellow Report: Physics of the HL-LHC, and HE-LHC perspectives.

  • July 2019: 64 ATLAS contributions given at the European Physics Society High Energy Physics 2019 conference in Ghent, Belgium. ATLAS highlights can be found at http://atlas.cern/updates/atlas-news/eps-2019-highlights .

  • Spring 2019 : Success of the AAP (Call for Project) of the Aix-Marseille AMIDEX fundation for the AIDAQ project: This project deals with the implementation of artificial intelligence algorithms on FPGAs (in particular of neural networks) for the real time computation of the energies deposited in the ATLAS Liquid Argon Calorimeter.

  • January 2019 - now: LHC Long Shutdown 2 and on-going ATLAS detector Phase I Upgrade targetting Run 3 data taking. Our group is a strong contributor to the installation of the new readout electronics for the electromagnetic calorimeter.

  • December 2018: End of proton-proton data taking (Run 2 Phase), with a record collected luminosity of 139 fb-1 which will lead to precision analysis of the Higgs boson properties, as well as searches for New Physics in an extended mass range.

  • 13th November 2018: Aix-Marseille Thesis award 2017 given to Thomas Calvet. This work comes in recognition of his excellent research work on the assocatied Higgs production with a quark top pair where the Higgs decays to two bottom quarks (so-called ttH(bb) channel), and the b jet tagging with the ATLAS experiment at the LHC. https://hal-amu.archives-ouvertes.fr/tel-01681700/

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 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 2024.
  • 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 2024.

They both have a strong discovery potential in the next ten years.

The Time Projection Chamber and the veto are equipped with 200 000 Silicon PhotoMultipliers (SiPM). All these components are embedded in a proto-DUNE-like cryostat.

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 2024. 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.

The Time Projection Chamber and the veto are equipped with 200 000 Silicon PhotoMultipliers (SiPM). All these components are embedded in a proto-DUNE-like cryostat.

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 μ\mu eV, favored by the theory. Currently in an R&D phase, it aims to start data taking with a prototype in 2024 and with the final detector in 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.

Preliminary baseline design of the Madmax approach, showing the magnet, the booster consisting of the mirror (copper disk at the far left) and the 80 dielectric disks, the focusing mirror and the receiver, consisting of the horn antenna and the cold preamplifier inside a separated cryostat. At the extreme right the final expected signal is shown.

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 (Bsμ+μB_s\to\mu^+\mu^- , BsJ/ψϕB_s \to J/\psi \phi ) 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 4σ4 \sigma from the theoretical predictions. We are specifically studying the rare modes with τ\tau in the final state, B(s)Kττ,Kτμ,ττ,τμ B(s) \to K^{\ast} \tau \tau , K \tau \mu, \tau \tau, \tau \mu , and the ratio between the branching ratios R(D)=BR(BDτν)/BR(BDμν)R (D^{\ast} ) = BR(B \to D^{\ast} \tau \nu) / BR(B \to D^\ast \mu \nu) .
