Muon (g ? 2) and XENON1T excess with boosted dark matter in L ? L model

Motivated by the growing evidence for lepton flavour universality violation after first results from Fermilab's muon $(g-2)$ measurement, we revisit one of most widely studied anomaly free extensions standard model namely, gauged $L_{\mu}-L_{\tau}$ model, known to be providing a natural explanation $(g-2)$. We also incorporate presence dark matter (DM) in this order explain recently reported electron recoil excess XENON1T collaboration. show that same neutral gauge boson responsible generating required can mediate interactions between and fermions boosted annihilation. The DM annihilation rate into fermion require hybrid setup thermal non-thermal mechanisms generate relic density. tightly constrained parameter space all requirements remain sensitive ongoing near future experiments, keeping scenario very predictive.
