Are pairs of Higgs bosons more interesting than just one ?
Louis D'Eramo (CERN/Northern Illinois University)
Voir détails Cacher détails
Description :
The current description of the electroweak symmetry breaking relies on an Higgs field associated with an additional potential term in the SM Lagrangian. That mechanism is an extraordinary but yet puzzling fundamental piece for explaining the mass of elementary particles. The discovery of the Higgs boson at the LHC was the first milestone to confirm this theory, measuring one of the free parameters introduced. Since then, most of the predicted couplings of this boson to SM particles have been measured, and are in excellent agreement with the theoretical predictions. Nowadays, more attention has been raised on measuring the second free parameter: the Higgs self-interaction. 
In this regard, the Higgs pair production is particularly sensitive to this coupling, while presenting a stimulating challenge due to the limited statistics available. In this talk, I present recent results from the ATLAS collaboration on measurements of HH production as predicted by the Standard Model and its possible enhancement through coupling modification or with the search for beyond-SM physics involving resonances producing HH pairs.

Wellbeing - a forgotten ingredient in academic success
Ewa Pluciennicka (PhDSuccess)
Voir détails Cacher détails
Description :

Mental Health of early career researchers is alarming. Several recent studies reported that PhD candidates are at a high risk of developing mental health disorders such as depression, anxiety, and burn-out. Importantly, Evens (2018) found that PhD students are 6 times more likely to develop mental health disorders in comparison with other highly educated individuals working outside of academia. Finally, Satinsky et al. 2021 showed that despite the growing evidence of mental health dangers for academics, little attention has been given to the ways to improve it and urged for more practical solutions.

In the light of these findings, the aim of this intervention is 1) to raise mental health awareness among academics 2) reduce the risks of developing mental disorders and finally 3) propose a practical solutions on how researchers can take care of their mental health, despite the challenging working environment. In particular, in this 1-hour seminar, studies on mental health and wellbeing in academia will be presented explaining the causes and prevalence of mental distress, followed by practical advice on how to detect and prevent mental health risks at the early stages and how to enhance wellbeing and life satisfaction on a daily basis.

Finally, in line with numerous studies indicating that “happy” employees are more motivated, present better resilience to stress, and are more efficient at work, we believe that improving the mental health of PhD researchers will benefit them individually, but also contribute to creating better working environment and potentially result in better work/research effectiveness for academic institutions.

AMS-02: 10 years of cosmic-rays measurements on the International Space Station
Laurent Derome (LPSC)
Voir détails Cacher détails
Description :
In May 2010, the AMS-02 experiment was installed on the International Space Station. Since then, the experiment continuously detects the cosmic ray particles with energies ranging from sub-GeV to several TeV. The AMS-02 detectors allow to measure the components of the cosmic rays, electrons/positrons, protons, antiprotons and all the nuclei from helium to iron with an unprecedent precision.
In this presentation, I will present the AMS-02 project, the instrumentation implemented to identify and measure the energy of cosmic ray particles as well as the main results from the experiment. In particular, I will present the measurement of positrons and antiprotons and discuss the interpretation of these measurements in the framework of dark matter searches and the measurement of galactic cosmic ray nuclei which allows the study of the sources and the propagation of cosmic rays.

Loop quantum gravity: from discrete spacetime to gravitational waves
Simone Speziale (CPT Marseille, CNRS)
Voir détails Cacher détails
Description :

I will briefly review some of the key properties of general relativity
that make its quantization so unlike the other fundamental forces. I
will explain how the approach known as loop quantum gravity faces this
challenge, and give a pedagogical introduction to the main ideas
behind it. The resulting scenario of a quantum and discrete spacetime
has already led to a broad phenomenology targeting observations from
primordial cosmology and black holes. I will then describe more recent
work, which explores the consequences that some of the loop quantum
gravity assumptions have in the structure of gravitational waves, and
which could potentially open new paths to phenomenology.

Gravitational wave astronomy with GRANDMA
Sarah ANTIER (Artemis, OCA)
Voir détails Cacher détails
Description :

The multi-messenger astronomy aims to study astrophysical events through different messengers : GW, photons, neutrinos. The 170817 joint detection of GW and photons (at all wavelengths) has proven the relevance of multi-messengers studies. Yet it also showed the necessity of coordination and preparation of electromagnetic observations (from gamma to radio) to have relevant constraints on physical parameters. In this talk, I will present the Global Rapid Advanced Network Devoted to the Multi-messenger Addicts (GRANDMA), a network of telescopes aiming to detect, identify and characterize electromagnetic counterparts to gravitational-wave sources. I will detail the consortium, its capabilities, scientific program and public tools developed for the time domain astronomy. I will conclude by presenting a summary of our scientific results after O3 LIGO/Virgo run and the prospects we will be conducting to prepare the next GW observation runs (and possibly KM3NET campaigns).
