Nonleptonic decays: Amplitude analysis and supermultiplet schemes
R Delbourgo, Dongsheng Liu
We give best covariant amplitude decompositions for two-body decay processes involving ground state hadrons () and show how these are simply related to…

QCD improved estimates to rare B-Decays at the heavy b-quark limit
Dongsheng Liu
The renormalization effects from the b-quark scale down to the non-perturbative QCD regime are studied for rare -decays at the heavy b-quark limit. Phenomenological consequences…

Long Distance Contributions to B-Decays into Higher K-Resonances
Mohammad R. Ahmady, Dongsheng Liu, Zhijian Tao
We use the new symmetries in the heavy quark limit to calculate the exclusive B-decays where are higher resonances of K-meson. We then estimate the long…
