Constraining Non-Standard Interactions with Coherent Elastic Neutrino-Nucleus Scattering at the European Spallation Source

Résumé

We investigate the possibility of constraining non-standard neutrino interactions (NSI) through high-statistics measurements of coherent elastic neutrino-nucleus scattering (CEvNS) at the European Spallation Source. Considering the different proposed detection technologies, we study the sensitivity to neutral-current NSI parameters that each detector can reach in 3 years of data taking. We show that operating two detectors simultaneously can significantly improve the sensitivity on flavor-diagonal NSI parameters. Combining the results of two detectors turns out to be even more useful when two NSI parameters are assumed to be nonvanishing at a time. In this case, suitably chosen detector combinations can reduce the degeneracies between some pairs of NSI parameters to a small region of the parameter space.
