Abstract
In this letter we present the analytic results for the two-loop corrections to the Wilson coefficients C9(muW) and C10(muW) in type-I and type-II two-Higgs-doublet models at the matching scale muW. These corrections are important ingredients for next-to-next-to-leading logarithmic predictions of various observables related to the decays B -> Xs l+ l- in these models. In scenarios with moderate values of tan(beta) neutral Higgs boson contributions can be safely neglected for e,mu. Therefore we concentrate on the contributions mediated by charged Higgs bosons.
