Abstract
We study the possibility of explaining the recently found anomalies in B-meson decays within scenarios with a composite Higgs boson. This class of models provides a natural way to fit the experimental results, interpreting the anomalies as the result of the exchange of heavy vector resonances with electroweak quantum numbers. The anomalies are tightly related to deviations in Delta F = 2 transitions and to deformations of the Z and W couplings, whose size is of the order of the present experimental bounds. This leads to a very predictive scenario which could be soon tested at collider experiments.
