Possible single resonant production of the fourth-generation charged leptons at gamma e colliders

Abstract

Single resonant productions of the fourth-standard-model-generation charged leptons via anomalous interactions at gamma e colliders based on future linear e(+)e(-) colliders with 500 GeV and 1 TeV center-of-mass energies are studied. Signatures of gamma e -> l(4) -> e gamma and gamma e -> l(4) -> eZ anomalous processes followed by the hadronic and leptonic decay of the Z-boson and corresponding standard-model backgrounds are discussed.
