CP-Violating and Charged Current Neutrino Non-standard Interactions in CE$\nu$NS

Understand

Neutrino non-standard interactions (NSI) can be constrained using coherent elastic neutrino-nucleus scattering.

• We discuss here two aspects in this respect, namely the effects of (i) charged current NSI in neutrino production and (ii) CP-violating phases associated with neutral current NSI in neutrino detection.
• Effects of CP-phases require the simultaneous presence of two different flavor-changing neutral current NSI parameters.
• Applying these two scenarios to the COHERENT measurement, we derive limits on charged current NSI and find that more data is required to compete with the existing limits.
