Testing minimal flavor violation in leptoquark models of the RK∗ $$ {R_K}_{{}^{\left(\ast \right)}} $$ anomaly

Abstract The RK∗ $$ {R_K}_{{}^{\left(\ast \right)}} $$ anomaly can be explained by tree level exchange of leptoquarks. We study the consequences of subjecting these models to the principle of minimal flavor violation (MFV). We consider MFV in the linear regime, and take the charged lepton Yukawa mat...
