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. 

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?

The Deep Underground Neutrino Experiment (DUNE) is a 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
 
This ambitious program also includes the search for Nucleon Decay and the astrophysical observations of Galactic Supernovae. 

Le progrès impressionnant réalisé récemment par le ProtoDUNE Dual Phase a été publié conjointement par le CERN et Fermilab.
