Muonphilic asymmetric dark matter at a future muon collider

Abstract

A bstract We explore phenomenological constraints on, and future muon collider sensitivities to, the parameter spaces of various muonphilic portals to fermionic asymmetric dark matter (ADM). Both WEFT-level dimension-6 effective operators and two UV models based on gauged L μ – L τ are considered. One of the latter features a vector coupling to the dark matter and the other an axial vector coupling. The ADM cri..
