Abstract

Recently, Tevatron released their measurements on the invariant mass spectrum of electron and positron, as well as the dijet arising from WW+WZ production, with one W decaying leptonically. Although the statistics are not significant, there are two bumps around 240 GeV and 120–160 GeV, respectively. We proposed that the two bumps correspond to the extra-light gauge bosons Z′ and W′, which couple with quarks with deci-weak strength. In this brief report, we also simulated dijet invariant mass distribution at the current running LHC.
