Direct determination of Wilson coefficients using $B^0\to K^{\ast 0}{\mu }^{+}{\mu }^{-}$ decays

T. Hurth, C. Langenbruch, F. Mahmoudi

A method to directly determine the Wilson coefficients for rare $b\to s$ transitions using $B^0\to K^{\ast 0}{\mu }^{+}{\mu }^{-}$ decays in an unbinned maximum likelihood fit is presented. The meth…
