Global fits to b → sll data and signs for lepton non-universality

There are some slight tensions with the SM predictions within the latest LHCb measurements. Besides the known anomaly in one angular observable of the rare decay B --> K*mu(+)mu(-), another small discrepancy recently occurred. The ratio R-K = BR(B+ --> K+mu(+)mu(-))/BR(B+ --> K(+)e(+)e(-)) in the low-q(2) region has been measured by LHCb showing a 2.6 sigma deviation from the SM prediction. In contrast to the anomaly in the rare decay B --> K*mu(+)mu(-) which is affected by power corrections, the ratio R-K is theoretically rather clean. We analyse all the b --> sll data with global fits and in particular explore the possibility of breaking of lepton universality. Possible cross-checks with an analysis of the inclusive B --> X(s)l(+)l(-) decay are also explored.
