Sim-to-real adaptation in the KM3NeT/ORCA detector

Neutrino physics is one of the most exciting topics in contemporary physics, leading to two Nobel prizes in the last 20 years for the detection of cosmic neutrinos and the discovery that neutrinos have mass. The massive nature of neutrinos is arguably the strongest indication of physics beyond the Standard Model of particle physics, opening a number of fundamental questions: What is the mechanism for neutrino mass generation? Are neutrinos responsible of the matter-antimatter imbalance in the universe? Can neutrinos tell us something about the unification of fundamental forces?

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.

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.
b) Run 2 (2015–2018), at an energy of 13 TeV in the c.o.m, with greater integrated luminosity which allowed the observation of the main fermionic interactions of the Higgs boson (H → tt,  H → bb, ttH production).

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.
