The Rumble in the Meson: a leptoquark versus a Z′ to fit b → sμ$^{+}$μ$^{−}$ anomalies including 2022 LHCb $ {R}_{K^{\left(\ast \right)}} $ measurements
We juxtapose global fits of two bottom-up models (an S$_{3}$ scalar leptoquark model and a B$_{3}$ – L$_{2}$Z′ model) of b → sμ$^{+}$μ$^{−}$ anomalies to flavour data in order to quantify statistical preference or lack thereof. The leptoquark model couples directly to left-handed di-muon pairs, wher...
