摘要
We examine the prospects of searching for dilepton gauge bosons in e(-)p colliders. Specifically we take a SU(3)(C) x SU(3)(L) x U(1)(X) model and calculate the cross section for the process, e(-)p --> e(+) + D + anything mediated by doubly-charged dilepton gauge bosons, where D is a new quark predicted by the model. At HERA, with center-of-mass energy root s=314 GeV and the integrated luminosity 100 pb(-1), we can obtain the signature of dileptons with mass up to 340 GeV (650 GeV) if D has a mass lighter than 200 GeV (150 GeV). At LEPII-LHC, with center-of-mass energy root s=1790 GeV and an anticipated luminosity 6 fb(-1)yr(-1), we expect more than 280 events per year provided that both the mass of dileptons and that of the D-quarks is less than 1 TeV.
