Invoking Chiral Vector Leptoquark to explain LFU violation in B Decays

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.
