Description
Coherent elastic neutrino-nucleus scattering (CEνNS) has been demonstrated to be an essential tool to investigate key electroweak physics parameters and nuclear properties since its first observation in 2017 by COHERENT.
In this presentation, we review the results obtained using the latest COHERENT CsI and Ar and Dresden-II Ge datasets which allow us to achieve a measurement of the neutron distribution radius Rn of 133Cs, 127I, 40Ar and of the weak mixing angle (WMA).
For the first time, we compare and combine the COHERENT data with the atomic parity violation experimental result on Cs and proton-Cs elastic scattering, to obtain the most precise data-driven determination of the low-energy weak mixing angle, independent of the value of the neutron distribution radius. Moreover, we discuss the current agreement between all available determinations of Rn and of the WMA using electroweak and non-electroweak probes, finally performing a global fit of all available determinations.
To conclude, prospects for the future will be reviewed.
