Studies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays
We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
متن کاملویژگیهای نیمفلزی و پایداری ساختاری ترکیبات نیمهویسلر d0-d XYBi (X=K, Rb; Y=Sc, Ti, V, Cr)
با استفاده از محاسبات اصول اولیة ساختار الکترونی در چارچوب نظریة تابعی چگالی، ویژگیهای الکترونی، مغناطیسی و پایداری ساختاری ترکیبات نیمهویسلر d0-d جدید XYBi (X=K, Rb; Y=Sc, Ti, V, Cr) مورد بررسی قرار گرفت. نتایج نشان میدهد که ۶ مورد از این ترکیبات شاملKCrBi ،RbVBi ،KVBi ،RbTiBi ،KTiBi و RbCrBi فرومغناطیسهای نیم-فلزی میباشند. گاف انرژی نیمفلزی این ترکیبات در محدودة ۴۶/۰ تا ۷۱/۰ الکترونولت...
متن کاملThe d-precoloring problem for k-degenerate graphs
In this paper we deal with the d-Precoloring Extension problem, (d-PrExt), in various classes of graphs. The d-PrExt problem is the special case of precoloring extension problem where, for a fixed constant d, input instances are restricted to contain at most d precolored vertices for every available color. The goal is to decide if there exists an extension of given precoloring using only availa...

متن کاملOn D-Wave Meson Spectroscopy and the K∗(1410)-K∗(1680) Problem
The mass spectrum of D-wave mesons is considered in a nonrelativistic constituent quark model. The results show a common mass degeneracy of the isovector and isodoublet states of the 1 D1 and 1 D3 nonets, and suggest therefore that the K∗(1680) cannot be the I = 1/2 member of the 1 D1 nonet. They also suggest that the η2(1870), presently omitted from the Meson Summary Table, should be interpret...
