Abstract
Production of doubly charged Higgs bosons via the s-channel process e−e−→ H–→ l−l− at future linear collider energies is studied by taking into account initial state radiation (ISR) and beamstrahlung (ISR+BS), final state radiation (FSR) and detector smearing effects. The discovery bounds of lepton flavour conserving and violating couplings are obtained for doubly charged Higgs bosons. It is found that future linear colliders with centre of mass energies and will be able to probe the doubly charged Higgs bosons with diagonal couplings down to 10−4 and 10−3, respectively.
