Factorization in non-leptonic decays of heavy mesons
John F. Donoghue, Alexey A. Petrov
Abstract
We propose a QCD-based model for calculation of the non-perturbative corrections to the factorization approximation in the decays of heavy mesons. In the framework of the model, factorization in pseudoscalar transitions holds exactly at the leading order leaving the opportunity to calculate non-leading corrections consistently.
