Heavy Leptons

We study the pair production of new heavy leptons within a new U(1)′ symmetry extension of the Standard Model. Because of the new symmetry, the production and decay modes of the new heavy leptons would be different from those of three families of the standard model. The pair production cross-sections depending on the mixing parameter and the mass of heavy leptons have been calculated for the center-of-mass energies of 0.5 TeV, 1 TeV and 3 TeV. The accessible ranges of the parameters have been obtained for different luminosity projections at linear colliders. The search can be performed within the range of mixing parameter -1<x<-0.35 and 0.05<x<1, given that the heavy lepton mass Ml′ = 400 GeV at [Formula: see text] and L int = 100 fb -1. We find the sensitivity to the range of mixing parameter -1<x<1 for the mass range Ml′<800 GeV at [Formula: see text] and L int = 100 fb -1.

Heavy Leptons

We investigate the single and pair production of new heavy leptons via string inspired E6 model at future linear colliders. Signal and corresponding backgrounds for these leptons are studied. We have found that single production of heavy leptons is more relevant than that of pair production, as expected. For a maximal mixing value of 0.1, the upper mass limits of 2750 GeV in the single case and 1250 GeV in the pair production case are obtained at [Formula: see text] collider option.
