New Limits on Doubly Charged Bileptons from CERN LEP Data and the Search at Future Electron-Positron and Electron-Photon Colliders

E. M. Gregores, A. Gusso, S. F. Novaes

We show that the accumulated LEP-II data taken at $\sqrt{s}=$ 130 to 206 GeV can establish more restrictive bounds on doubly charged bileptons couplings and masses than any other…
