7. Detector R&D for Future High-Energy Colliders: Instrumentation and Deep Learning Developments for the Timing-SDHCAL

William VAGINAY (CNRS - IP2I)

24/04/2026 09:10

As a brief introduction, the Semi Digital Hadronic Calorimeter (SDHCAL) is a concept of a gaseous hadronic calorimeter based on Resistive Plate Chamber (RPC) technology, originally designed for the future linear collider ILC. In the context of future circular colliders such as FCC and CEPC, an upgraded version - the Timing SDHCAL (T-SDHCAL) - is currently under development. It incorporates...

19. Introduction to Higgs physics: search for Higgs pair production with CMS

Eva DIDIER-ESTEVE (IP2I)

24/04/2026 09:25

Since the discovery of the Higgs boson in 2012, the main goal of the CMS collaboration has been to characterize the Higgs boson and measure its potential. One of the most important characteristics to measure is the Higgs boson self-coupling $\lambda$: this fundamental parameter is notably responsible for the breaking of the electroweak symmetry during the Big Bang and possibly of the...

2. Dualities and correspondances in supersymmetric gauge theories

Timothé ALEZRAA (IP2I, Lyon)

24/04/2026 09:40

I will summarize and give hints to exact results in quantum field theory, and algebraic/geometric intepretation of correspondances between seemingly very different quantum theories.

16. Preliminary measurement of the germanium ionisation yield and first studies of the new silicon crystal detectors of the Ricochet experiment

Tatiana LE BELLEC (IP2I)

24/04/2026 09:55

Coherent elastic neutrino nucleus scattering (CEvNS) was first measured experimentally by the COHERENT experiment in 2017 and is currently being studied by many experiments all around the world. In this context, the Ricochet international collaboration aims to detect the CEvNS process in order to search for new physics. The detectors used are germanium crystals operated at cryogenic...

17. The RICOCHET experiment : status and prospects

Romain Faure (IP2I MANOIR)

24/04/2026 10:10

The RICOCHET experiment is operated by an international collaboration that aims to observe coherent elastic neutrino-nucleus scattering (CEνNS) to reveal deviations in the electroweak sector from the Standard Model of particle physics. The setup is situated 8.8m from the core of research reactor at the Institut Laue-Langevin (ILL, Grenoble, France). The detection principle consists in...
