Perturbative QCD study on the photonic penguin contributions to the decay B -> K*gamma
Source PublicationEUROPEAN PHYSICAL JOURNAL C
KeywordBbar-meson Decay B->s-gamma Decay Model
AbstractIncluding corrections of order O(m(K)*/m(B)), we present an analysis of photonic penguin contributions to the decay B --> K*gamma 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.
