On observed flavour anomalies and their potential explanation by leptoquarks:

With the recent result [[of LHCb]], for the first time a single observable affected by negligible theoretical uncertainties exhibits a deviation from the SM exceeding the 3σ3 \sigma level. Equally striking is the overall coherence of the picture that emerges, especially in bs + b \to s \ell^+ \ell^- −transitions. As we shall show in this paper, combining all the bs + b \to s \ell^+ \ell^-−observables in a very conservative way, the significance of the New Physics (NP) hypothesis formulated in 2014–2015 of a purely left-handed LFU-violating contact interaction has now reached a significance of 4.6σ4.6 \sigma.

[][\ldots] A more structural way of addressing the flavor structure of the model is the idea of implementing Pati-Salam unification
