Anomalies in B-meson decays reported by the LHCb experiment could be explained by introducing a heavy neutral gauge boson Z' that dominantly couples to third generation quarks and second generation leptons. While the sensitivities of inclusive searches for such models are strong in heavy Z' regions (>500 GeV), the low-mass region sensitivity is degraded by large SM background (mostly Drell-Yan process).
A Z' boson production, decaying to two muons, through bottom-quark fusion processes is studied. We assume an associated production with jets, at least one of them bottom-tagged. This complementary search is shown to improve sensitivities for low Z’ mass regions beyond the inclusive analyses.
