Doubly charged Higgs from e–γ scattering in the 3-3-1 Model

Abstract

We studied the production and signatures of doubly charged Higgs bosons in the process γe⁻→H⁻⁻E⁺, where E⁺ is a heavy lepton, at the e⁻e⁺ International Linear Collider (ILC) and CERN Linear Collider (CLIC). The intermediate photons are given by the Weizsäcker–Williams and laser-backscattering distributions. We found that significant signatures are obtained by bremsstrahlung and backward Compton scattering of laser. A clear signal can be obtained for doubly charged Higgs bosons, doubly charged gauge bosons and heavy leptons.
