New Models Propose Inelastic Scalar Dark Matter to Explain LUX-ZEPLIN Signal

Researchers have introduced new theoretical models, including a U(1)_{B-3L_τ} framework, to interpret a 248 keV nuclear-recoil signal observed by the LUX-ZEPLIN experiment. These models suggest an inelastic scalar dark matter candidate with an 840 GeV complex scalar, also exploring implications for higgsino dark matter. This preliminary, non-peer-reviewed work aims to advance understanding of dark matter properties.
