The leptophilic dark matter with $Z^{\prime }$ interaction: from indirect searches to future $e^{+}{e}^{-}$ collider searches

Ning Chen, Jian Wang, Xiao-Ping Wang

We investigate the scenario where the dark matter only interacts with the charged leptons in the standard model via a neutral vector mediator $Z^{\prime }$. Such a scenario with a 430 GeV d…
