摘要：

In an e-p collider, a striking signature for a dilepton gauge boson is e-p --> e+mu-mu-+ anything; this cross section is calculated by using the helicity amplitude technique. At HERA, with center-of-mass energy square-root s = 314 GeV, a dilepton mass above 150 GeV is inaccessible but at LEPII-LHC, with a center-of-mass energy square-root s = 1790 GeV, masses up to 650 GeV can be discovered. In an e+e- collider, the signature is e+e- --> 2e+2mu- or 2e-2mu+. The cross sections of this process are also calculated for the center-of-mass energies square-root s = 200, 500 and 1000 GeV.
