B?J/?(?,K) Decays within QCD Factorization Approach

We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...

Efficient (j, k)-domination

A dominating set S of a graph G is called efficient if |N [v]∩S| = 1 for every vertex v ∈ V (G). That is, a dominating set S is efficient if and only if every vertex is dominated exactly once. In this paper, we investigate efficient multiple domination. There are several types of multiple domination defined in the literature: k-tuple domination, {k}-domination, and k-domination. We investigate ...

In between k -Sets, j -Facets, and i -Faces: (i , j) - Partitions

Let S be a finite set of points in general position in Rd. We call a pair (A,B) of subsets of S an (i, j)-partition of S, if |A| = i, |B| = j and there is an oriented hyperplane h with S∩h = A and with B the set of points from S on the positive side of h. (i, j)-Partitions generalize the notions of k-sets (these are (0, k)-partitions) and j-facets ((d, j)-partitions) of point sets as well as th...

Crystal Structure of Nonaaquayttrium(III) Bromate at 100 K

The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...
