Realistic search for doubly charged bileptons at linear $e^{-}e^{-}$ collider energies
We search for doubly charged scalar bileptons via $ \text{e}^{-}\text{e}^{-}\to μ^{-}μ^{-}$ and $ \text{e}^{-}\text{e}^{-}\to \text{e}^{-}\text{e}^{-}$ processes at linear collider energies by considering initial and final state electromagnetic radiative corrections (ISR, FSR). Moreover, smeared cross section is used for finite energy resolution. We show that ISR+FSR and smearing reduce cross sections remarkably depending on the smearing parameter due to narrow decay width of bileptons. We obtain realistic discovery contours of couplings and masses for the lepton flavour conserving and violating processes.
