Study of the beyond standard model interaction using coherent elastic neutrino-nucleus scattering process

A bstract We have conducted an extensive study that highlights the potential of the Indian Coherent Neutrino-nucleus Scattering Experiment (ICNSE) detector in constraining neutrino-quark interactions that go beyond the standard model. By utilizing reactors with varied core configurations and power outputs as sources for electron antineutrinos, and operating with a target mass of 10 kg over a year, our findings reveal that the ICNSE detector is remarkably effective in narrowing down the vast majority of the Non-standard Interaction (NSI) parameter space. Moreover, incorporating results from two distinct detectors, like sapphire and high-purity germanium, markedly enhances sensitivity by reducing the degeneracies between some pairs of NSI parameters to a smaller region. This research highlights its role in enabling future developments and investigations.
