Description
I will highlight recent advances in astroparticle physics phenomenology, with a particular emphasis on coherent elastic neutrino-nucleus scattering (CEvNS) and Dark Matter (DM). CEvNS has recently been observed in low-threshold neutrino and DM direct detection experiments: a) by the COHERENT collaboration utilizing neutrinos from pion decay at rest, and b) induced by solar neutrino scattering off the Xe targets of XENONnT and PandaX-4T experiments. These new data offer exciting physics opportunities both within and beyond the Standard Model (SM). CEvNS serves as a unique tool for conducting SM precision tests at low energies, such as determining the weak mixing angle. Additionally, it provides complementary constraints to those obtained from large-scale oscillation and accelerator experiments, for a set of motivated new physics scenarios. The latter include non-standard interactions (NSIs), sterile neutrinos, violation of lepton unitarity, electromagnetic neutrino properties etc., with direct implications for the neutrino floor in DM searches. Looking at the wider picture, in the final part of the talk I will discuss how neutrino experiments can facilitate studies that extend beyond the neutrino sector. Special attention will be given to searches for axion-like particles (ALPs), underscoring the versatility of these experimental setups in probing new physics.
