We investigate models of a heavy neutral gauge boson Z coupling mostly to third generation quarks and second generation leptons. In this scenario, bottom quarks arising from gluon splitting can fuse into Z allowing the LHC to probe it. In the generic framework presented, anomalies in B-meson decays reported by the LHCb experiment imply a flavor-violating bs coupling of the featured Z constraining the lowest possible production cross section. A novel approach searching for a Z() in association with at least one bottom-tagged jet can probe regions of model parameter space existing analyses are not sensitive to.
