Leptophilic scalar dark matter in U(1)${}_{L_{\mu }-L_{\tau }}$: Evading direct detection and prospective neutron star heating

Chengfeng Cai, Hong-Hao Zhang

Leptophilic dark matter (DM) is a well-motivated thermal weakly interacting massive particle framework that can evade stringent nuclear-recoil searches while remaining testable via…
