The study reveals the need for sizable hadronic contributions and correlations among them in the context of recent measurements on B0, B+ -> K*(0,)(+) mu(+)mu(-) decays. By extending the analysis to b -> sl(+)l(-) data, it was found that the fully left-handed operator scenario stands out as the simplest with a significance of almost 6 sigma.
We perform an analysis within the Standard Model of B-0,B-+ -> K*(0,)(+) mu(+)mu(-) decays in light of the recent measurements from the LHCb experiment, showing that new data strengthen the need for sizable hadronic contributions and correlations among them. We then extend our analysis to new physics via the Standard Model effective theory, and carry out a state-of-the-art fit of available b -> sl(+)l(-) data, including possible hadronic contributions. We find the case of a fully left-handed operator standing out as the simplest scenario with a significance of almost 6 sigma.
