Realistic constraints on the doubly charged bilepton couplings from Bhabha scattering with LEP data
Abstract
Upper limits on doubly charged bilepton couplings and masses are extracted from LEP data for Bhabha scattering at energy range s=183-202 GeV using standard model program ZFITTER which calculates radiative corrections. We find that gL2/ML2<O(10-5)GeV-2 at 95% C.L. for scalar and vector bileptons.
