Implications of the first detection of coherent elastic neutrino-nucleus scattering (CEvNS) with Liquid Argon

Understand

The CENNS-10 experiment of the COHERENT collaboration has recently reported the first detection of coherent-elastic neutrino-nucleus scattering (CEvNS) in liquid Argon with more than $3 \sigma$ significance.

• In this work, we exploit the new data in order to probe various interesting parameters which are of key importance to CEvNS within and beyond the Standard Model.
• A dedicated statistical analysis of these data shows that the current constraints are significantly improved in most cases.
• We derive a first measurement of the neutron rms charge radius of Argon, and also an improved determination of the weak mixing angle in the low energy regime.
