Mesure de désintégrations hadroniques du boson de Higgs et calorimètre électromagnétique du Futur Circular Collider

The student will perform, with simulated event samples, a study of the sensitivity of the measurement of Higgs boson decays to hadrons at the Futur Circular Collider, for the measurement of the Higgs Yukawa couplings to quarks of the second and third families.
In addition, the student will also have the possibility - if time allows - to work on the detailed simulation of the electromagnetic calorimetry section of one of the proposed detector designs for FCC.

The DUNE Vertical Drift detector and its potential to measure the leptonic CP-violating phase with sub-GeV atmospheric neutrinos

Higgs Boson Physics at complementary Colliders, through the search for double-Higgs boson production in the bb final state for the measurement of the Higgs boson self-coupling at the LHC, and prospects for Higgs boson mass, ZH cross section and Higgs Se

The ATLAS experiment is installed at the Large Hadron Collider (LHC) at CERN near Geneva, Switzerland. Two data taking periods have already taking place:
a) Run 1 (2011–2012), at 7 and 8 TeV in the center of mass (c.o.m). In this Run ATLAS and CMS discovered a standard model-like Higgs boson at 125 GeV (H), mainly through its bosonic decay modes.

Search for double-Higgs boson production in the bb+2 photon final state for the measurement of the Higgs boson self-coupling and prospects for Higgs boson coupling studies to quarks and gluons at future colliders

The main subject of this thesis is the analysis of the Run3 data of the ATLAS experiment at the Large Hadron Collider at CERN for the search of the production of two Higgs bosons for the measurement of its self-coupling.

Le boson de Higgs a dix ans !

Il y a dix ans, le 4 juillet 2012, les collaborations ATLAS et CMS annonçaient la découverte d'une nouvelle particule cohérente avec le boson de Higgs du modèle standard (SM) de la physique des particules utilisant les collisions proton-proton délivrées par le Large Hadron Collider (LHC ) au CERN.
Cette découverte a marqué un progrès fondamentale de la physique des particules en raison du rôle clé joué par le boson de Higgs dans l’interpretation théorique des phénomènes microscopiques fournie par le SM [1].

Neutrino reconstruction in the DUNE experiment using Machine Learning

The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino oscillation experiment under construction in the US. A neutrino beam will be produced at the Fermi National Accelerator Laboratory (FNAL) in Illinois, by colliding accelerated protons into a target.

Impact of instrumental noise on direct dark matter search with DarkSide-20k

Dark Matter is one of the main puzzles in fundamental physics and Weakly Interacting Massive Particles (WIMP) are among the best-motivated dark matter particle candidates. As of today, the most sensitive experimental technique to discover the WIMPs in the mass range from 2 GeV to 10 TeV is the dual phase Time Projection Chamber (TPC) filled with noble liquids. DarkSide-20k is the next generation of Liquid Argon (LAr) TPC, which will be running at LNGS (Italy) from 2024 with 50-ton active mass.
