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). 

Direct dark matter search in liquid argon 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. 

The Borexino scientific collaboration, an experiment at the Gran Sasso National Laboratories, publishes today, November 25th, 2020, in Nature the announcement of the first ever detection of neutrinos produced in the Sun by the CNO cycle (carbon-nitrogen-oxygen). It is an experimental result of historical value, which completes a chapter of physics that started in the 1930 decade of the last century. The implication of this new measure for understanding stellar mechanisms is enormous: in fact, since the CNO cycle is predominant in the most massive stars than the Sun,...

The Deep Underground Neutrino Experiment (DUNE)

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.

On Monday, 20 April 2020, the Double Chooz international collaboration publishes its latest result in Nature Physics (Hervé de Kerret et al).  Read more about it


In response to the COVID-19 pandemic and the resulting shortage of ventilators, the DarkSide collaboration develops a new model of easily produced and low-cost mechanical ventilators. A prototype has already been made and is now being tested in an Italian hospital.
