Preprint Proposes Scalar Signal Interpretation for LUX-ZEPLIN Nuclear Recoil Event

Researchers have submitted a preprint suggesting an interpretation for a 248 keV nuclear-recoil candidate observed by the LUX-ZEPLIN experiment. The paper introduces an anomaly-free U(1)_{B-3L_\tau} model, where an 840 GeV complex scalar undergoes an endothermic transition. This theoretical framework could potentially explain the observed event and link it to dark matter phenomenology.
