CE$\nu$NS as a probe of flavored generalized neutrino interactions

TL;DR

This paper investigates how coherent-elastic neutrino-nucleus scattering experiments can constrain exotic neutrino interactions beyond the Standard Model, using recent and projected data from multiple detectors.

Contribution

It provides the first combined analysis of scalar, vector, and tensor flavored GNI parameters using COHERENT data and forecasts constraints with future reactor-based detectors.

Findings

Reactor data significantly tighten constraints on electron flavor GNI.

Combined analysis improves bounds on exotic couplings.

Future experiments will enhance sensitivity to new physics.

Abstract

We examine the potential to probe generalized neutrino interactions (GNI), exotic effective couplings due to new physics interactions beyond the Standard Model, in the coherent-elastic neutrino-nucleus scattering experiments in light of the latest COHERENT-CsI, and -LAr data. Our analysis focuses on scalar, vector and tensor flavored-GNI parameters. A combined analysis has been made to constrain these exotic couplings for the CsI and LAr detector. We further add the projected forthcoming reactor-based Scintillating Bubble Chamber detector to examine these couplings. It has been observed that the addition of reactor data strongly constrained electron flavor GNI.
