The next generation of dark matter (DM) direct detection (DD) experiments are becoming sensitive to the scattering of solar neutrinos.
It will be the first time coherent elastic neutrino-nucleus scattering (CEvNS) will be detected from incident solar neutrinos, as opposed to spallation sources. Simultaneously, it will provide a complementary measurement of solar neutrinos via elastic neutrino-electron scattering. In this talk I will highlight the implications of these novel signals as a new means of testing neutrino non-standard neutrino interactions (NSI).
For this purpose, I will introduce a convenient parameterization of the NSI parameter space that allows for an easy visualisation of the complementarity of different experimental sources. I will then contrast the sensitivities of DM DD experiments on NSIs with previous results from spallation sources and neutrino oscillation experiments, highlighting the importance of including DD experiments in future global fits of the NSI landscape.
