1/m(b)(2) corrections to the left-right lepton polarization asymmetry in the decay B->X(s)mu(+)mu(-)

Using a known result by Falk et al. for the 1/m(b)(2) correction to the dilepton invariant mass spectrum in the decay B-->X(s) mu(+)mu(-), we calculate the 1/m(b)(2) correction to the left-right muon polarization asymmetry in this decay. Employing an up-to-date range of values for the nonperturbative parameter lambda(1), we find that the correction is much smaller than should have been expected from the previous work by Falk et al.
