Strong-interaction effects in weak radiative [formula omitted] decay

Abstract

Strong-interaction corrections to the effective hamiltonian for weak radiative B - meson decay (i.e., B → X s γ , where X s denotes a strange hadronic final state) are calculated using the leading logarithmic approximation. The inclusive rate for decays B → X s γ , where the energy of the photon is large, is computed in the standard model with minimal particle content and in extensions of the minimal standard model with two Higgs doublets.
