A direct detection view of the neutrino NSI landscape

A bstract In this article, we study the potential of direct detection experiments to explore parameter space general non-standard neutrino interactions (NSI) via solar scattering. Due their sensitivity neutrino-electron and neutrino-nucleus scattering, provides a complementary view NSI landscape that spallation sources oscillation experiments. particular, large admixture tau neutrinos in flux makes well-suited probe full flavour NSI. To this, develop re-parametrisation framework explicitly includes variable electron contribution allows for clear visualisation complementarity different experimental sources. Using new parametrisation, how previous bounds from source are impacted. For first time, compute limits on results XENONnT LUX-ZEPLIN experiments, obtain projections future xenon-based These computations have been performed with our newly developed software package, SNuDD. Our demonstrate importance using more parametrisation indicate next generation will become powerful probes
