CP violating effects in coherent elastic neutrino-nucleus scattering processes

Understand

The presence of new neutrino-quark interactions can enhance, deplete or distort the coherent elastic neutrino-nucleus scattering (CEvNS) event rate.

• The new interactions may involve CP violating phases that can potentially affect these features.
• Assuming light vector mediators, we study the effects of CP violation on the CEvNS process in the COHERENT sodium-iodine, liquid argon and germanium detectors.
• We identify a region in parameter space for which the event rate always involves a dip and another one for which this is never the case.
