Probing light mediators and (g ? 2)? through detection of coherent elastic neutrino nucleus scattering at COHERENT

A bstract We present the constraints on parameters of several light boson mediator models obtained from analysis current data COHERENT CE ? NS experiment. consider a variety vector models: so-called universal, B ? L and other anomaly-free U(1)? gauge with direct couplings new neutrinos quarks, e ? , ? where coupling quarks is generated by kinetic mixing photon at one-loop level. also model scalar that assumed, for simplicity, to have universal leptons. Since are well-fitted cross section predicted Standard Model, yields mass depend charges in each under consideration. compare these limits experiments values can explain muon g 2 anomaly couples mediator.
