This paper presents an analysis of current and future dark matter direct detection (DD) experiments, focusing on the potential of solar neutrino-induced elastic neutrino-electron scattering (EνES) to probe new physics beyond the Standard Model (SM). The study analyzes data from the XENONnT, LUX-ZEPLIN (LZ), and PandaX-4T experiments, and provides constraints on several $ U(1)^{\prime} $ extensions of the SM, including the anomaly-free B-L model, lepton flavor-dependent interactions, and other models with extended gauge sectors. The results are compared with existing bounds from terrestrial and astrophysical experiments, and forecasts are provided for future experiments like DARWIN.
The analysis considers the effects of new vector mediators on the EνES process, which can arise in various $ U(1)^{\prime} $ models. These models include the B-L model, $ B-2L_{e}-L_{\mu,\tau} $, $ B-3L_{\alpha} $, $ L_{\alpha}-L_{\beta} $, and $ L_{e}+2L_{\mu}+2L_{\tau} $ models. The study provides bounds on the coupling and mass of light vector mediators for these models, based on current data from the XENONnT, LZ, and PandaX-4T experiments. The results are compared with other bounds from the literature, and the study highlights the potential of future experiments like DARWIN to improve these bounds.
The paper also discusses the role of solar neutrinos in DD experiments, noting that while they constitute a background for dark matter searches, they also provide opportunities to probe neutrino properties and new physics connected to the neutrino sector. The study shows that current DD experiments have the potential to probe new physics in the neutrino sector through EνES induced by solar neutrinos, and that future experiments like DARWIN could significantly improve these bounds. The results are presented in the form of 90% confidence level (C.L.) exclusion limits for various models, with comparisons to other experimental bounds. The study concludes that current DD experiments provide competitive constraints for certain mass ranges, while future experiments like DARWIN will offer further improvements. The results are also compared with astrophysical and cosmological observations, highlighting the complementarity of different experimental approaches.This paper presents an analysis of current and future dark matter direct detection (DD) experiments, focusing on the potential of solar neutrino-induced elastic neutrino-electron scattering (EνES) to probe new physics beyond the Standard Model (SM).
