Dilepton Production in $e^{-}p$ and $e^{+}{e}^{-}$ Colliders

Abstract

In an $e^{-}p$ collider, a striking signature for a dilepton gauge boson is \ep \ ; this cross-section is calculated by using the helicity amplitude technique. At HERA, with center-of-mass energy $\sqrt{s}=314GeV$, a dilepton mass above $150GeV$ is inaccessible but at LEPII-LHC, with a center-of-mass energy $\sqrt{s}=1790GeV$, masses up to 650 GeV can be discovered. In an $e^{+}{e}^{-}$ collider, the signature is \ee \ . The cross-sections of this process are also calculated for the center-of-mass energies $\sqrt{s}=200,500$ and $1000GeV$.
