Non-standard neutrino interactions in U(1)′ model after COHERENT data

Abstract

We explore the potential to prove light extra gauge Z boson inducing nonstandard neutrino interactions (NSIs) in the coherent-elastic neutrino-nucleus scattering (CEνNS) experiments. We intend to examine how the latest COHERENT-CsI and CENNS-10 data can constrain this model. A detailed investigation for the upcoming Ge, LAr-1t, and NaI detectors of COHERENT collaboration has also been made. Depending on numerous other constraints coming from oscillation experiments, muon (g −2), beam-dump experiments, LHCb, and reactor experiment CONUS, we explore the parameter space in Z boson mass vs coupling constant plane. Moreover, we study the predictions of two-zero textures that are allowed in the concerned model in light of the latest global-fit data.

Implications of the first detection of coherent elastic neutrino-nucleus scattering (CEvNS) with liquid Argon

“…The discovery of coherent elastic scattering of neutrinos off nuclei at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL) using a CsI detector [2] has opened new ways to study key weak interaction parameters, such as the electroweak mixing angle [3,4] and the nuclear form factors [5][6][7], as well as to probe novel neutrino properties beyond the Standard Model (SM) [8]. Among the most interesting possibilities, are those addressing non-standard interactions (NSI) [9][10][11][12][13][14][15][16][17][18][19], electromagnetic neutrino properties [20][21][22][23][24], sterile neutrinos [25][26][27][28], new light mediators [29][30][31][32][33][34][35] and dark matter [36,37]. The study of these scenarios would provide important hints for physics beyond the current three-massive-neutrino paradigm of elementary particles.…”

The physics potential of a reactor neutrino experiment with Skipper CCDs: measuring the weak mixing angle

“…For example, light mediators coupling to standard model particles have been searched for in the CONNIE experiment [19]. On the theoretical side, there are several studies evaluating the physics capabilities of CEvNS experiments, including the following: CEvNS cross section measurements [20,21], nuclear physics probes [22], neutrino non-standard interactions [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37], axion-like particles [38], light mediators and neutrino electromagnetic prop-…”

Flavor-dependent radiative corrections in coherent elastic neutrino-nucleus scattering

“…This new way of detecting neutrinos has attracted a great deal of attention from the high-energy community. The possibility of doing neutrino physics with relatively small detectors in the kg [5][6][7][8][9] to tonne [10][11][12][13] scale, as opposed to 100-tonne [14][15][16][17] or even JHEP02(2021)097 kiloton detectors [14,15,18], opens up the possibility of competitively measuring neutrino properties with small-scale projects [6,8,[19][20][21]. CEνNS provides an unavoidable background floor for dark matter direct detection [22][23][24][25][26][27][28][29][30][31][32][33][34][35].…”
