Title: Phenomenology of a lepton triplet

Abstract

The most general phenomenological model involving a lepton triplet with hypercharge {+-}1 is constructed. A distinctive feature of this model is the prediction of a doubly charged lepton and a new heavy Dirac neutrino. We study the phenomenology of these exotic leptons both in low-energy experiments and at the LHC. The model predicts flavor-changing neutral-current processes such as muon and tau rare decays, which are studied in detail in order to constrain the model parameters. All the decay channels of the exotic leptons are described for a wide range of parameters. It is found that, if the mixing parameters between the exotic and light leptons are not too small (>10{sup -6}), then they can be observable to a 3-5{sigma} statistical significance at the 7 TeV LHC with 10-50 fb{sup -1} luminosity for a 400 GeV mass and 14 TeV with 100-300 fb{sup -1} luminosity for a 800 GeV mass.
