| Abstract | |
The LHCb measurements of the mu/e ratio in B -> Kll decays (R-K) indicate a deficit with respect to the Standard Model prediction, supporting earlier hints of lepton universality violation observed in the R-K({*}) ratio. Possible explanations of these B-physics anomalies include heavy Z' bosons or scalar and vector leptoquarks mediating b -> s mu(+)mu(-). We note that a muon collider can directly measure this process via mu(+)mu(-) -> b (s) over bar and can shed light on the lepton nonuniversality scenario. Investigating currently discussed center-of-mass energies root s = 3, 6 and 10 TeV, we show that the parameter space of Z' and leptoquark solutions to the RK({*}) anomalies can be mostly covered. Effective operators explaining the anomalies can be probed with the muon collider setup root s = 6 TeV and integrated luminosity L = 4 ab(-1). (AU) | |
