Observation of the color-suppressed decay B0 → d0π0
We report the first observation of color-suppressed B 0 → D 0 π 0 , D * 0 π 0 , D 0 η, and D 0 ω decays, and evidence for B 0 → D * 0 η and D * 0 ω. The branching fractions are B(B 0 → D 0 π 0 ) =Expand

Fat penguins and imaginary penguins in perturbative QCD
Abstract We evaluate B → Kπ decay amplitudes in perturbative QCD picture. It is found that penguin contributions are dynamically enhanced by nearly 50% compared to those assumed in the factorizationExpand
Leading-power contributions to B → π , ρ transition form factors
We calculate the $B\to\pi,\rho$ transition form factors in the framework of perturbative QCD to leading power of $1/M_B$, $M_B$ being the $B$ meson mass. We explain the basic principle by discussingExpand

QCD factorization for exclusive non-leptonic B-meson decays: General arguments and the case of heavy-light final states
We provide a rigorous basis for factorization for a large class of non-leptonic twobody B-meson decays in the heavy-quark limit. The resulting factorization formula incorporates elements of the naiveExpand
