摘要：
Purely leptonic B meson decays provide unique probes for physics Beyond the Standard Model. We study the impact of a scalar leptoquark, S1, on B. mu . decay. We find that, for mS1 1 TeV, the S1 leptoquark can modify the B. mu . rate significantly. Such a leptoquark can in principle also alter the B. t . rate. However, current searches from LHC and low energy physics provide some constraints on the parameter space.
