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].
 

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.

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.
