, decays with the QCD factorization approach
We studied the nonleptonic , decay with the QCD
factorization approach. It is found that the Cabibbo favored processes of
, , are the promising
decay channels with branching ratio larger than 1\%, which should be observed
earlier by the LHCb Collaboration.Comment: 15 pages, revtex4, version appeared in Advances in High Energy

On the Stability of Cooperation Structures
Qin [J. Eco. Th., 1996] recently showed that in a game of endogenous formation of cooperation structure, if the underlying TU-game is superadditive, then the full cooperation structure is stable. In this note, we characterize the class of games that ensure the stability of the full cooperation structure, and show that this class is much larger than that of superadditive TU-games.Cooperation structure, graph, Myerson value, stability
