Abstract: (Springer)

The collection of a few anomalies in semileptonic B-decays invites to speculate about the emergence of some strikingly new phenomena. Here we offer a possible interpretation of these anomalies in the context of a weakly broken

U(2)^5

flavor symmetry and leptoquark mediators.

Note:

16 pages, 4 figures

B: semileptonic decay
symmetry: flavor
anomaly
U(2)
mediation
leptoquark: pair production
B: branching ratio: ratio
B --> K lepton+ lepton-
B --> D*(2010) lepton antineutrino
operator: dipole
