COHERENT constraints on $Z^{\prime }$ in 331$\beta$ model

Abstract

We investigate coherent-elastic neutrino-nucleus scattering ($CE\nu NS$) in 3-3-1 models for different values of $\beta$ in which $\beta$ is a parameter used to define the charge operator of the 331 models. We show that the number of events predicted by 331$\beta$ model is in agreement with the data given by COHERENT experiment. We evaluate the sensitivity of the mass of Z' boson with 90% confidence level (CL) and find that $m_{Z^{\prime }}\ge 1.4$TeV for $\beta =-\sqrt{3}$ with 90% CL. We perform ${\chi }^2$ fit for liquid Argon, Germanium and NaI detector subsystems, we obtain $m_{Z^{\prime }}\ge [2,3.1]$ TeV with 90\% CL. Our results indicate low-energy high-intensity measurements can provide a valuable probe, complementary to high energy collider searches at LHC and electroweak precision measurements.
