Description

B anomalies attract a lot of attention in the last few years. The charged current caused ratios of the taounic semileptonic B decays to D() and the muonic one indicate deviations from the standard model prediction. In the case of flavor changing neutral current processes ratio of muonic and electronic in B to K() transitions and similar transitions of b to s l+ l- in various decays again, there are deviations of measured and theoretically predicted values. In both anomalies, the differences are on the level 3 to 4 standard deviations. The presence of new particles usually explains both anomalies. I will review existing proposals of new physics and their consequences on theoretical and experimental studies.
