Bottom-quark fusion processes at the LHC for probing \u3ci\u3eZ\u27\u3c/i\u3e models and \u3ci\u3eB\u3c/i\u3e-meson decay anomalies

Abstract

We investigate models of a heavy neutral gauge boson Z\u27 coupling mostly to third generation quarks and second generation leptons. In this scenario, bottom quarks arising from gluon splitting can fuse into Z\u27 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\u27 constraining the lowest possible production cross section. A novel approach searching for a Z\u27(→ μμ) in association with at least one bottom-tagged jet can probe regions of model parameter space existing analyses are not sensitive to
