Description
The decay B0->K*0mu+mu- is a rare b->s transition and as such strongly suppressed in the Standard Model (SM), allowing for sensitive searches for New Physics contributions. A method to determine the Wilson coefficients directly from this decay is presented, which does not rely on binning the available data in the invariant di-lepton mass squared, q2. The method shows improved precision compared to the conventional approach of using q2-binned angular observables. It is furthermore shown that it will be possible to use the direct fit method with the combined Run 1 and Run 2 data sample taken by the LHCb experiment.
