@misc{10481/30597, year = {2007}, url = {http://hdl.handle.net/10481/30597}, abstract = {A new leptophobic neutral gauge boson Z' with small mixing to the Z can have a mass as light as M_Z' ~ 350 GeV, and still have escaped detection at LEP and Tevatron. Such a Z' boson can be derived from E6 and, if the new heavy neutrino singlets in the 27 representation are lighter than M_Z'/2, the process p p(pbar) -> Z' -> NN -> l+- l+- X is observable. Indeed, this new signal could explain the small excess of like-sign dileptons found at Tevatron. Implications for LHC are also discussed. In particular, the Tevatron excess could be confirmed with less than 1 fb-1, and leptophobic Z' masses up to 2.5 TeV can be probed with 30 fb-1.}, organization = {This work has been supported by MEC project FPA2006-05294 and Junta de Andalucía projects FQM 101 and FQM 437.
