Query: Understanding the B->K*mu+mu- Anomaly   We present a global analysis of the B->K*(->K pi)mu+mu- decay using the
recent LHCb measurements of the primary observables P_{1,2} and P'_{4,5,6,8}.
Some of them exhibit large deviations with respect to the SM predictions. We
explain the observed pattern of deviations through a large New Physics
contribution to the Wilson coefficient of the semileptonic operator O9. This
contribution has an opposite sign to the SM one, i.e., reduces the size of this
coefficient significantly. A good description of data is achieved by allowing
for New Physics contributions to the Wilson coefficients C7 and C9 only. We
find a 4.5 sigma deviation with respect to the SM prediction, combining the
large-recoil B->K*(->K pi)mu+mu- observables with other radiative processes.
Once low-recoil observables are included the significance gets reduced to 3.9
sigma. We have tested different sources of systematics, none of them modifying
our conclusions significantly. Finally, we propose additional ways of measuring
the primary observables through new foldings.
