The P5' anomaly uncovered by the LHCb experiment in B → K^*μμ angular observables has motivated a possible Z' boson that couples to left-handed b → s transitions, where a model would be gauged Lμ- Lτ symmetry, but direct search for such a Z' is not promising. Less constrained is an analogous Z' coupling to right-handed t → c transitions. Motivated by this, we study cg → tZ' associated production at LHC, both for a generic model, and in Lμ- Lτ with a vector-like U quark. We also study c c → Z' production that exists within the model. Both processes can be probed already with LHC Run 2 data, all the way up to the HL-LHC with discovery potential.
