Abstract

We show that a single vector leptoquark can explain both the muon g-2 anomaly recently measured by the Muon g-2 experiment at Fermilab, and the various B decay anomalies, including the R_D^(*) and R_K^(*) anomalies which have been recently reported by the LHCb experiment. In order to provide sizeable positive new physics contributions to the muon g-2, we assume that the vector leptoquark particle couples to both left-handed and right-handed fermions with equal strength. Our model is found to satisfy the experimental constraints from the large hadron collider.
