Doubly resonant WW plus jet signatures at the LHC

We present search prospects and phenomenology of doubly resonant signals that come from the decay of a neutral weak-singlet color-octet vector state ω_8 into a lighter weak-triplet color-octet scalar π_8, which can arise in several theories beyond the Standard Model. Taking m_{ω_8}-m_{π_8}>m_W, we demonstrate an analysis of the signals pp \to ω_8 \to π^\pm_8 W^\mp (π^0_8 Z) \to g W^\pm W^\mp (g Z Z). The present 8 TeV LHC run is found to have the potential to exclude or discover the signal for a range of masses and parameters. The preferred search channel has a boosted W-tagged jet forming a resonance with a second hard jet, in association with a lepton and missing energy.
