"The shape of (new) physics in B decays"
Anomalies in (semi)leptonic $B$-meson decays present interesting patterns
that might be revealing the shape of the new physics to come. I will
review the decays and observables where these appear, discussing the extent
up to which the respective SM predictions are understood. In this sense,
the most interesting anomaly is the violation of lepton universality
suggested by a recent measurement of a deficit of $B^+\to K^+\mu\mu$ over
$B^+\to K^+ee$ decays. This raises very interesting questions concerning
the lepton-flavor structure of the presumed new interactions, some of
which I will address in the context of effective operators and a
particular class of models of new physics. Finally, I will discuss new
possible experiments that could unambiguously confirm and characterize
the putative new-physics effect.
