Probing lepton-number-violating couplings of doubly-charged Higgs bosons at an e(-)e(-) collider

The doubly charged Higgs bosons Delta(--) that are present in exotic Higgs representations can have lepton-number-violating couplings to e(-)e(-) We discuss general constraints and phenomenology for the Delta(--) and demonstrate that extremely small values for the e(-)e(-) --> Delta(--) coupling-squared (some 8 orders of magnitude smaller than the current limit) would produce observable signals for Delta(--) production in direct s-channel production at an e(-)e(-) collider.
