Gauged L μ − L τ at a muon collider
We investigate the sensitivity of the projected TeV muon collider to the gaugedLμ−Lτ model. Two processes are considered: Z′-mediated two-body scatterings μ+μ−→ℓ+ℓ− with ℓ=μ or τ and scattering with initial state photon emission,μ+μ−→γZ′,Z′→ℓ¯ℓ, where ℓ can be μ, τ, or νμ/τ. We quantitatively study...
