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 ... -
Calculated solar-neutrino capture rate for a radiochemical 205Tl-based solar-neutrino detector
Kostensalo, Joel; Suhonen, Jouni; Zuber, K. (American Physical Society, 2020)Radiochemical experiments for low-energy solar-neutrino detection have been making headlines by exploiting the isotopes 37Cl and 71Ga. Such a very low-threshold measurement of this type can also be performed using 205Tl, ... -
Theoretical predictions of wimp-nucleus and neutrino-nucleus scattering in context of dark matter direct detection
Pirinen, Pekka (University of Jyväskylä, 2018)The nature of dark matter is at present an open question. Assuming the main component of dark matter consists of weakly interacting massive particles (WIMPs), directly detecting such particle via a scattering process ... -
Dimuons from neutrino-nucleus collisions in the semi-inclusive DIS approach
Helenius, Ilkka; Paukkunen, Hannu; Yrjänheikki, Sami (Springer Nature, 2024)We present a next-to-leading order perturbative QCD calculation of dimuon production in neutrino-nucleus collisions. This process is typically calculated by assuming it to be proportional to inclusive charm production, ... -
