DarkSide-50
darkside.lngs.infn.it
is searching for dark matter particles via their collisions with argon nuclei.
We rely on rejecting any other particle interactions in deep underground laboratories. The
"undeground" argon, has much lower intrinsic radioactivity with respect to "atmospheric" argon.
We contributed to detector commissioning and are involved in data analysis.

DarkSide-20k
We are also working on the development of detectors components for the future DarkSide-20k detector. LAr
technology has unique background rejection capabilities to reach sensitivities up to and beyond
so called ”neutrino floor”, where neutrino-induced coherent scattering on nuclei starts
contributing to the background.

DUNE large-scale international LAr experiment will investigate the pattern of neutrino mass and
mixing, and the role they play in astrophysics and cosmology.
We are presenty involved in HV Dune/ProtoDune
Consortium.

MARLEY (ongoing) = development of realistic MC generator for low energy neutrino interactions in LAr.
ACED (ongoing)= a precision measurement of the gamma capture spectra fron neutron capture on argon with DANCE detector at LANL.
ARIS R&D project
aris.in2p3.fr
Argon Recoil Ionization and Scintillation (ARIS) experiment made
precision measurements of low energy argon nuclei recoils induced by monoenergetic directional
neutrons in an argon detector and investigated if detector response depends
on the argon recoil direction with respect to the applied electric field. These measurements
provided several important scientific inputs for current and future LAr based experiments
designed for direct detection of dark matter particles.

SiGHT photosensor R&D
Development of novel hybrid photosensor SiGHT with a less challenging design,
enhanced performance and radiopurity to further advance dark matter searches. We collaborate
with UCLA group on this project.
