Probing the liquid argon response to low-energy nuclear recoils for light dark matter detection with DarkSide

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 1 GeV/c2 to 10 TeV/c2 is the dual phase Time Projection Chamber (TPC) filled with noble liquids. The “dual-phase” approach has the main advantage to provide simultaneous access to the ionization and to the scintillation signals.

DUNE - study of the effect of detector-related systematic uncertainties


The Deep Underground Neutrino Experiment (DUNE) is a next-generation long baseline neutrino experiment which aims to:
Discover CP Violation in the leptonic sector 
Determine the neutrino Mass Ordering 
Precisely measure neutrino oscillation parameters
Test the 3-flavour paradigm

The two upcoming long baseline experiments, DUNE  and HyperK, herald a new era of precision for the measurement of the oscillation parameters, by achieving high statistics and (critically) by controlling the associated systematic uncertainties.

Etude de performances attendues au futur collisionneur circulaire electron-positron FCC-ee

Le candidat travaillera au sein du groupe ATLAS/FCC de l’equipe Particules d’APC. 

Il etudiera les performances (de reconstruction de particules dans le detecteur ou des analyses de physique sur les proprietés du boson de Higgs) attendues au futur collisionneur circulaire d’electrons et positrons, le FCC-ee, proposé pour prendre le relais apres la fin du programme experimental du Large Hadron Collider (LHC) du CERN.

Neutrino oscillations in the high frequency regime

Neutrino oscillation computations are one of the bottlenecks in performing data analyses of atmospheric neutrinos. The high frequency regimes at lower energies are particularly challenging as the fast oscillations need to be averaged to account for the limited resolution of the detector.

In this internship, the student will learn how to use the OscProb package and will implement a new solution for efficiently averaging oscillations in the high frequency regime.

Measuring the Neutrino Mass Ordering with KM3NeT/ORCA and JUNO

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?
