ResumoThe coupling of the baryonic current to new neutrino states ${\ensuremath{\nu}}_{b}$ with strength in excess of the weak interactions is a viable extension of the standard model. We analyze the signature of ${\ensuremath{\nu}}_{b}$ 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 ${\ensuremath{\nu}}_{b}$ 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.
