Solution of sign problem in heavy meson decays: nonfactorizable soft gluons in nonleptonic heavy meson decays

arXiv:hep-ph/9712527

Abstract

For the first time, a solution to the sign problem in heavy meson decay based on PQCD factorization theorems. The point is to include QCD evolution effort characteristic scales involved in decay processes.
