Attached “On the flavour anomalies and connections to new physics” report by María Ramos (UAM ESR) and Xavi Ponce (INFN ESR)
Abstract: In the past years several deviations from the Standard Model were observed in semi-leptonic charged and neutral currents, which became known as the B-anomalies. In this short article, we review the mostmupdated experimental results that constrain these observables as well as their new physics interpretation. In particular, we discuss a minimal model comprising a singlet and a leptoquark that could explain not only these deviations, but also the anomalous results associated to the muon magnetic moment and the extraction of the Cabibbo angle.

(Top-right) Preferred region of the model parameters for exotic masses of 5.5TeV. (Bottom-right) Contributions of the model to RD(∗) , assuming the parameter space defined in the upper panel. The green and yellow bands are within 1σ and 2σ of the best fit point, respectively.
