Lifetimes of Charmed Hadrons Revisited. Facts and fancy
Boris Blok, Michael Shifman
The problem of the hierarchy of lifetimes of charmed hadrons is reviewed. The QCD-based theory of preasymptotic effects in inclusive weak decays dating back to the beginning of the…

Nonperturbative QCD efects in weak hadronic decays
B. Blok, M. Shifman
QCD-based analysis of nonfactorizable parts of weak nonleptonic amplitudes is reported. Nonperturbative effects due to soft gluon exchange play a key role leading to the emergence…
