Xiao-Ping Wang, You-Kai Wang, Bo Xiao, Jia Xu, Shou-hua Zhu
TL;DR
This paper suggests that two observed bumps in Tevatron data may be due to new light gauge bosons, $Z'$ and $W'$, with deci-weak couplings, and provides simulation results for LHC.
Contribution
It proposes a novel interpretation of experimental bumps as light $Z'$ and $W'$ bosons with deci-weak couplings, supported by simulation analysis.
Findings
Two bumps at 120-160 GeV and 240 GeV may indicate new gauge bosons.
Simulated di-jet mass distributions at LHC support the hypothesis.
The proposed bosons have deci-weak coupling strengths.
Abstract
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 and , 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.
