A very active subfield in high energy physics recently is the study of hadrons with heavy-light quark content [1]. A major effort has been spent in calculating the Isgur-Wise function, which, once it is determined, can be widely used in calculations of heavy meson decay (b → c) processes. After an initial exploration [2], calculations of the Isgur-Wise function on the lattice [3– 5] have quickl...

The protein CTCF plays an essential role in the action of a widely distributed class of vertebrate enhancer-blocking insulators, of which the first example was found in a DNA sequence element, HS4, at the 5' end of the chicken beta-globin locus. HS4 contains a binding site for CTCF that is necessary and sufficient for insulator action. Purification of CTCF has revealed that it interacts with pr...

We simulate the measurement of the triscalar Higgs coupling at LHC(8,14) via pair production of h(125 GeV). We find that the most promising hh final state is bb̄γγ. We account for deviations of the triscalar coupling from its SM value and study the effects of this coupling on the hh cross-section and distributions with cut-based and multivariate methods. Our fit to the hh production matrix eleme...

Already in the past, hadronic τ decays have served as an interesting source to obtain information on the parameters of the Standard Model, like the strong coupling αs or the strange quark mass. Below it will be shown that the approach to obtain the strange mass from the hadronic τ-decay width can be turned into a determination of the CKM matrix element Vus, once the strange mass is used as an i...

In this paper a composite plate with similar unidirectional fibers is considered. Assuming orthotropic structure, theory of elasticity is used for investigating the stress concentration. Also, complex variable functions are utilized for solving the plane stress problems. Then the effective characteristics of this plate are studied numerically by using ANSYS software. In this research a volume e...

We use QCD sum rules to determine the twist-two non–singlet operator matrix elements and fixed x structure functions paying particular regard to the estimate of the errors. Particularly for the matrix element determination, we find large uncertainties due to radiative and higher dimension contributions. We consider the origin of these large corrections and comment on their consequences for othe...

We extend the algorithm for matching fixed-order tree-level matrix element generators with the Dipole Cascade Model in ARIADNE to apply to processes with incoming hadrons. We test the algoritm on for the process W+n jets at the Tevatron, and find that the results are fairly insensitive to the cutoff used to regularize the soft and collinear divergencies in the tree-level matrix elements. We als...

Wepresent the combinatorial design for a kind ofmatrices called all-adjacency matrices. Such a matrix is constructed from a given set of elements; each element of the matrix is adjacent, within some column, to every other element of the set. We present the algorithm for constructing an all-adjacency matrix. These matrices have an important application—to the laying out of logical disks in a sha...
