Abstract

Coherent elastic neutrino-nucleus scattering (CE$\nu$NS) is a well-predicted Standard Model (SM) process only recently observed for the first time. It provides a novel window to search for physics beyond the SM (BSM). Electromagnetic properties of neutrinos (neutrino magnetic moment, charge radius and milli-charge) are the type of possible topics to be investigated in this channel. The subject is a direct implication of the observed non-vanishing neutrino mass from experimental evidence to describe solar neutrino problem. These properties can be also used to determine whether neutrinos have a Dirac or Majorana nature. As one of the densest natural sources of neutrinos on Earth, solar neutrinos provide a stable flux for CE$\nu$NS experiments. The recoil energy region of the solar neutrino CE$\nu$NS process falls within the same target range of direct detection experiments of WIMPs. This makes it an important component of the neutrino floor, as well as a suitable target signal for detection. In this work, we present the event rates of the CE$\nu$NS using solar neutrinos including effect of their electromagnetic properties. We also discuss the possibility to set limits on neutrino magnetic moments in the light of the latest CE$\nu$NS data reported by the CDEX-10 experiment.
