Heavy-lepton production via vector-boson fusion

We investigate the production of a possible pair of sequential heavy charged leptons ($M_L$∼200–800 GeV) at pp multi-TeV colliders via vector-boson fusion. The results are compared with the usual Drell-Yan mechanism and with the two-photon process. For very heavy leptons the fusion of W’s provides a contribution that is, at high energies, larger than the Drell-Yan mechanism.
