Description
Coherent elastic neutrino–nucleus scattering (CE$\nu$NS) provides a unique window into electroweak physics and potential extensions of the Standard Model. New data from a germanium detector collected by the COHERENT collaboration enable the most precise measurement of CE$\nu$NS to date.
In this talk, I present an analysis based on these data, focusing on their impact on key electroweak observables. By exploiting the high precision of the COHERENT germanium dataset, we extract improved constraints on the weak mixing angle, the neutron rms radius, and the neutrino charge radius. Our results are discussed in the context of the current state of the art, highlighting their consistency and competitiveness with existing measurements, as well as their implications for non standard neutrino interactions.
