Abstract:
LHCb has recently reported more than 2σ2σ deviation from the Standard Model prediction in the observable RJ/ψRJ/ψ. We study this anomaly in the framework of a vector leptoquark along with other lepton flavor universality violating measurements which include RK(∗)RK(∗), and RD(∗)RD(∗). We show that a chiral vector leptoquark can explain all the aforementioned anomalies consistently while also respecting other experimental constraints.
