A STUDY ON THE SEARCH POTENTIAL OF DOUBLY CHARGED LEPTONS AT THE SppC BASED ep COLLIDERS

Abstract

We consider the single production of doubly charged leptons which take part in the extended weak isospin models and have exotic electric charges such as  at the SppC based electron-proton (ep) colliders. We introduce the effective lagrangians describing the doubly charged lepton gauge interactions with SM leptons. We calculate the decay widths and production cross sections as a function of doubly charged lepton mass. We deal with the  process and plot the kinematical distributions for  the final state electron both for the signal and corresponding background. We perform a cut-based analysis to obtain the mass limits and couplings of doubly charged leptons at the SppC based ep colliders with the center-of-mass energies of TeV and  TeV.

Keywords

• doubly charged leptons,compositeness scale,electron-proton colliders,weak isospin
