We investigate models of a heavy neutral gauge boson Z' which could explainanomalies in B meson decays reported by the LHCb experiment. In these models,the Z' boson couples mostly to third generation fermions. We show that bottomquarks arising from gluon splitting can fuse into Z' as an essential productionmechanism at the LHC, thereby allowing to probe these models. The study isperformed within a generic framework for explaining the B anomalies that can beaccommodated in well motivated models. The flavor violating b s couplingassociated with Z' in such models produces lower bound on the productioncross-section which gives rise to a cross-section range for such scenarios forthe LHC to probe. Results are presented in Z' -> $\mu \mu$ decays with at leastone bottom-tagged jet in its final state. Some parts of the model parameterspace become constrained by the existing dimuon-resonance searches by the ATLASand CMS collaborations. However, the requirement of one or two additionalbottom-tagged jets in the final state would allow for probing a larger regionof the parameter space of the models at the ongoing LHC program.
