Solar Neutrinos as Background to Neutrinoless Double-beta Decay Experiments

Abstract

Solar neutrinos interact within double-beta decay (\BB) detectors and contribute to backgrounds for \BB\ experiments. Background contributions due to charge-current solar neutrino interactions with \BB\ nuclei of ${}^{76}$Ge, ${}^{82}$Se, ${}^{100}$Mo, ${}^{130}$Te, ${}^{136}$Xe, and ${}^{150}$Nd are evaluated. They are shown to be significant for future high-sensitivity \BB\ experiments that may search for Majorana neutrino masses in the inverted-hierarchy mass region. The impact of solar neutrino backgrounds and their reduction are discussed for future \BB\ experiments.
