Toward a Precision Measurement of CEvNS on Liquid Argon

The COHERENT collaboration has made measurements of the coherent elastic neutrino nucleus scattering (CEvNS) cross section on several targets. The first liquid argon measurement was made in 2021. The collaboration is currently undertaking precise measurements of the CEvNS cross section, the first of such measurements to be made on the liquid argon detector COH Ar 750. Making a precise measurement of the CEvNS cross section will also allow probing important standard model and beyond standard model physics quantities, such as the weak nuclear radius of Ar40 , neutrino oscillation parameters, non standard neutrino interactions, and more. Progress on COH Ar 750 will be presented as well as studies performed which can provide important upgrades to the detector in the future. Analysis of the expected event rates of signal and background predictions, and the detector’s ability to measure the weak radius of Ar40 , will also be presented.
