Elastic scattering signals of solar neutrinos with enhanced baryonic currents

TL;DR

This paper explores the potential detection of new neutrino states with enhanced baryonic currents through elastic scattering signals in dark matter and solar neutrino experiments, assessing their role in explaining experimental anomalies.

Contribution

It introduces a model of baryonic neutrinos with stronger-than-weak interactions and evaluates their detectability and implications for existing experimental anomalies.

Findings

Enhanced baryonic neutrino signals could explain DAMA, CoGeNT, and CRESST-II anomalies.

Current experiments place constraints on the baryonic neutrino model.

Detection prospects are promising for future underground rare event searches.

Abstract

The coupling of the baryonic current to new neutrino states \nu_b with strength in excess of the weak interactions is a viable extension of the Standard Model. We analyze the signature of \nu_b appearance in the solar neutrino flux that gives rise to an elastic scattering signal in dark matter direct detection and in solar neutrino experiments. This paper lays out an in-depth study of \nu_b detection prospects for current and future underground rare event searches. We scrutinize the model as a possible explanation for the reported anomalies from DAMA, CoGeNT, and CRESST-II and confront it with constraints from other null experiments.
