英文摘要	Including corrections of order O(m(K)/m(B)), we present an analysis of photonic penguin contributions to the decay B --> Kgamma in the perturbative QCD framework. Employing several models of the meson wave functions, we demonstrate that the corrections of O(m(K)*/m(B)) are enhanced and will provide substantial contributions to the decay because of the B meson wave function being sharply peaked (bound state effect). The numerical predictions for the corrections are about 30% similar to 60% which depend on the non-perturbative inputs such as the meson wave functions and the b-quark mass.
