### Description

Electrically-neutral massive color-singlet and color-octet vector bosons, common predictions of beyond the standard model physics, have the potential to be discovered as a resonance in a dijet channel at the LHC. A color-singlet resonance that has leptophobic couplings needs further investigation to be distinguished from the color-octet one. In previous work, we introduced a method for discriminating between the two kinds of resonance in the situation where their couplings are flavor-universal, using measurements of the dijet resonance mass, total decay width and production cross-section. Here, we describe an extension of that method to cover a more general and realistic scenario, in which the vector resonances could have flavor non-universal couplings, by incorporating measurements of the heavy-flavor decays of the resonance into the analysis. We present our analysis in a model-independent manner for a dijet resonance with mass $2.5-6.0 \,\mathrm{TeV}$ at the LHC with $\sqrt{s}=14\,\mathrm{TeV}$ and integrated luminosities $30,\,100,\,300$ and $1000\,\mathrm{fb}^{-1}$, where we found that our method is applicable in most scenarios.
