Abstract

The Higgs triplet model explains naturally the smallness of neutrino mass without right-handed neutrinos. In this work, we examine a singly charged Higgs boson of the model through elastic neutrino-electron scattering induced by solar neutrinos in dark matter direct detection experiments. It is embedded in the elastic neutrino-electron scattering, which is one of the background components in the experiments. Accordingly, we analyze the current low-energy electronic recoil data of PandaX-4T and XENONnT experiments. We place new limits on the ratio of coupling and mass of the charged Higgs boson. We also compare our findings with previous limits available in the literature. We obtain competitive results than some of the previous studies, marking the potential scrutiny of the model in the currently developing direct detection experiments.
