Des physiciens de l’APC parmi les lauréats du prestigieux “Breakthrough Prize” en physique fondamentale

Des scientifiques de l’APC comptent parmi les milliers de chercheurs du monde entier honorés par le Prix Breakthrough 2025 en physique fondamentale, décerné à la collaboration ATLAS du Grand collisionneur de hadrons (LHC) du CERN, aux côtés de ses expériences sœurs ALICE, CMS et LHCb

Higgs Physics at complementary colliders, with the search at LHC for double-Higgs production for the measurement of the Higgs self-coupling, and prospects for Higgs mass and self-coupling measurements at the Future Circular Collider in e+e- collisions

The following subject is for a Ph.D. thesis. An M1 or M2 stage can also be done on the Future Circular Collider topic (part b) of this ATLAS/FCC subject, as described here below.

Upgrade and performance of the ATLAS tracking detector and R&D on CMOS detectors for the new experiments at the Future Circular Collider

The ATLAS experiment is one of the four main detectors installed at the Large Hadron Collider (LHC) hosted by the CERN (cern.ch) laboratory, close to Geneva, Switzerland.
The data collected during Run1 (2010-2012) and Run2 (2015-2018) allowed to observe a Higgs boson (H) of a mass of about 125 GeV, first in bosonic final states and then in fermionic ones.
Run3 started in 2022, and should last till 2025, with the goal to integrate by that date about 450 fb^-1 of data, doubling those collected at the end of Run2.

Perpective studies on Higgs measurements with photons in ATLAS

This proposal is for a 3-month international internship at APC in the ATLAS group of the Particles team, between September and December 2023.
