Solar neutrino constraints on light mediators through coherent elastic neutrino-nucleus scattering

Abstract

We investigate new physics with light-neutral mediators through coherent elastic neutrino-nucleus scattering (CE$\nu$NS) at low energies. These mediators, with a mass of less than $1$ GeV, are common properties for extensions of the Standard Model (SM). We consider general scalar, vector, and tensor interactions allowed by Lorentz invariance and involve universal light mediators accordingly. In addition, we study an additional vector gauge boson with an associated $U(1{)}^{\prime }$ gauge group for a variety of models including $U(1{)}_{B-L}$, $U(1{)}_{B-3L_e}$, $U(1{)}_{B-3L_{\mu }}$, and $U(1{)}_{B-3L_{\tau }}$. These models differ in the fermion charges, which determine their contributions within the CE$\nu$NS process. The effects of each model are investigated by embedding them in the SM process using solar neutrino flux. We derive new limits on the coupling-mass plane of these models from the latest CDEX-10 data. We also present projected sensitivities involving the future experimental developments for each model. Our results provide more stringent constraints in some regions, compared to previous works. Furthermore, the projected sensitivities yield an improvement of up to one order of magnitude.
