FINDS

The FINDS (Fundamental Interactions aNd Dark Sectors) group is a dynamic team of 3 permanent physicists, 2 postdocs, and 3 PhD students dedicated to exploring new physics in two key areas:

  • Nuclear beta decay
  • Nuclear decays probing potential Dark Sector portals 

We actively support experiments at GANIL, focusing on fundamental interactions. Our members also lead the scientific coordination for the future DESIR facility, SPIRAL 1 beam developments, and the LISE spectrometer.

See more about DESIR here: https://www.ganil-spiral2.eu/scientists/ganil-spiral-2-facilities/experimental-areas/desir/

And LISE here: https://www.ganil-spiral2.eu/scientists/ganil-spiral-2-facilities/experimental-areas/d3-d6/

Our group leads several cutting-edge experiments:

  • MORA searches for signatures of CP violation in nuclear beta decay. A large CP violation is a crucial ingredient in explaining the universe’s matter-antimatter asymmetry. MORA is currently taking data at the university of Jyväskylä, in the IGISOL facility. See more about MORA here: https://mora.ganil-spiral2.eu/.
  • New JEDI investigates the existence of a new light gauge boson, potential portal to Dark Sectors, the so-called X17 boson, originally claimed to be observed in ATOMKI experiments. More information on New JEDI here: https://beyhan-bastin.cnrs.fr/new-jedi/
  • Precise branching ratio and half-life measurements in superallowed beta decay emitters, which are used to further constrain the Vud CKM matrix element. See more about this program in our recent publication in Physica Scripta: https://hal.science/hal-05009021v1
