In the past few years, attention has been drawn to the fact that a precision analysis of two-neutrino double beta decay (2υββ) allows the study of interesting physics cases like the emission of Majoron bosons and possible Lorentz symmetry violation. These processes modify the summed-energy distribution of the two electrons emitted in 2υββ. CUPID is a next-generation experiment aiming to exploit 100Mo-enriched scintillating Li2MoO4 crystals, operating as cryogenic calorimeters. Given the relatively fast half-life of 100Mo 2υββ and the large exposure that can be reached by CUPID, we expect to measure with very high precision the 100Mo 2υββ spectrum shape, reaching great sensitivities in the search for distortions induced by the physics beyond the Standard Model. In this contribution, we present the CUPID exclusion sensitivity for such New Physics processes, as well as the preliminary projected background of CUPID.

The first large-scale shell-model calculation of the two-neutrino double beta decay of 76Ge to the excited states in 76Se
Kostensalo, J.; Suhonen, J.; Zuber, K. (Elsevier, 2022)Large-scale shell-model calculations were carried out for the half-lives and branching ratios of the 2νββ decay of 76Ge to the ground state and the lowest three excited states 2+ 1 , 0+ 2 and 2+ 2 in 76Se. In total, the ... -
Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment

Challenges in double charge exchange measurements for neutrino physics
NUMEN Collaboration (CERN - the European Organization for Nuclear Research, 2019)The neutrinoless double beta (0νββ) decay, if observed, has important implications on particle physics, cosmology and fundamental physics. In particular it can give access to the effective neutrino mass. In order to extract ... -
