Event reconstruction and definition with DarkSide-20k for direct dark matter search in liquid argon

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 2025. 

Enhancing MeV physics at DarkSide-20k


The next challenges in neutrino and direct Dark Matter (DM) searches will require increasingly massive detectors, and increasingly complex, to cover a wide range of scientific goals.  The involved energy range extends from a few tens of eV induced by low mass WIMPs and neutrinos via coherent scattering, to solar neutrinos and neutrinoless double beta decay (~MeV scale), Supernova neutrinos (~10 MeV), and accelerator neutrinos (~GeV).  Experiments specifically designed for DM searches have the potential to explore the energy range up to Supernova neutrinos.

The Photon Detector System of the DUNE Vertical Drift module


The Deep Underground Neutrino Experiment (DUNE) is a next generation neutrino oscillation experiment. A high power wide-band beam operating in neutrino (anti-neutrino) mode will be produced at FNAL (Chicago). Some 1,300 km away, deep underground at the Sandford Underground Research Facility (South Dakota), four gigantic Far Detector modules will measure νμ (anti-νμ) disappearance, νe (anti-νe) and ντ (anti-ντ) appearance with the goals of:

Mise à niveau du détecteur de traces de l’expérience ATLAS et recherche de la production de di-Higgs dans l'état final bbγγ pour la mesure de l'auto-couplage du boson de Higgs

L’expérience ATLAS est installée auprès du Grand Collisionneur de Hadrons (LHC) du CERN à Genève. Il y a déjà eu deux longues séries de prises de données : 
a) le Run 1(2011–2012), à 7-8 TeV dans le centre de masse (c.d.m.), qui a permis à ATLAS et à CMS de découvrir un boson de Higgs à 125 GeV (H) principalement par ses désintégrations bosoniques (γγ et ZZ).
