Collider constraints and new tests of color octet vectors

We analyze the collider sensitivity for new colored resonances in t (t) over bar, b (b) over bar, and jj final states. While searches in the single production channel are model-dependent, the pair production rate is model independent and the existing (J J)(J J) and 4 t searches impose strong constraints on the relevant branching fractions, where J = j or b. We point out the missing, complementary searches in the mixed decay modes, t (t) over bar (j j), t (t) over bar (b (b) over bar), and (b (b) over bar)(j j). We propose analysis strategies for the t (t) over bar (j j) and t (t) over bar (b (b) over bar) decays and find their sensivity surpasses that of existing searches when the decay widths to tops and light jets are comparable. If no other decays are present, collective lower limits on the resonance mass can be set at 1.5TeV using 37 fb(-1) of 13 TeV data.
