Description
The LHCb experiment uncovered the P5' anomaly, a deviation in data from Standard
Model expectations in the said B -> K*mumu angular observable. This has motivated
a possible Z' boson that couples to left-handed b to s transitions, where a model
would be the gauged L_mu - L_tau symmetry, but direct search for such a Z' is not
promising. Less constrained is a similar Z', but coupling to right-handed t to c
transitions. Motivated by this, we study cg -> tZ' associated production at LHC,
both for a generic model, and in the L_mu - L_tau with a vector-like U quark as
its realization. We also study cc(bar) -> Z' production that would exist within
the model. Both processes can be probed already by LHC Run 2 data, all the way up
to the HL-LHC.
