Unraveling the Scotogenic Model at Muon Collider

Abstract

The Scotogenic model extends the standard model with three singlet fermion $N_i$ and one inert doublet scalar $\eta$ to address the common origin of tiny neutrino mass and dark matter. For fermion dark matter $N_1$, a hierarchical Yukawa structure $|y_{1e}|\ll |y_{1\mu }|\sim |y_{1\tau }|\sim \mathcal{O}(1)$ is usually favored to satisfy constraints from lepton flavor violation and relic density. Such large $\mu$-related Yukawa coupling would greatly enhance the pair production of charged scalar ${\eta }^{\pm }$ at the muon collider. In this paper, we investigate the dilepton signature of the Scotogenic model at a 14 TeV muon collider. For the dimuon signature ${\mu }^{+}{\mu }^{-}+/E_T$, we find that most viable samples can be probed with $200{\text{fb}}^{-1}$ data. The ditau signature ${\tau }^{+}{\tau }^{-}+/E_T$ is usually less promising but is important to probe the small $|y_{1\mu }|$ region. The mono-photon signature $\gamma +/E_T$ could also probe the compressed mass region $M_1\lesssim M_{{\eta }^{\pm }}$. Masses of charged scalar ${\eta }^{\pm }$ and dark matter $N_1$ can be further extracted by a binned likelihood fit of the dilepton energy.
