  Recently Tevatron released their measurements on invariant mass spectrum of
electron/positron, as well as the di-jet arising from WW+WZ production with one
W leptonically decay. Though the statistics is 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 $Z^\prime$ and $W^\prime$,
which couple with quarks with the deci-weak strength. In this brief report, we
also simulated di-jet invariant mass distribution at the current running LHC.
