Evidence for in-medium changes of four-quark condensates.
Utilizing the QCD sum rule approach to the behavior of the omega meson in nuclear matter we derive evidence for in-medium changes of particular four-quark condensates from the recent CB-TAPS experiment for the reaction gamma + A --> A' + omega(--> pi0gamma) with A = Nb and LH2.
متن کاملTriple factorization of non-abelian groups by two maximal subgroups
The triple factorization of a group $G$ has been studied recently showing that $G=ABA$ for some proper subgroups $A$ and $B$ of $G$, the definition of rank-two geometry and rank-two coset geometry which is closely related to the triple factorization was defined and calculated for abelian groups. In this paper we study two infinite classes of non-abelian finite groups $D_{2n}$ and $PSL(2,2^{n})$...
متن کاملFactorization and Non-factorization in Diffractive Hard Scattering
Factorization, in the sense defined for inclusive hard scattering, is discussed for diffractive hard scattering. A factorization theorem similar to its inclusive counterpart is presented for diffractive DIS. For hadron-hadron diffractive hard scattering, in contrast to its inclusive counterpart, the expected breakdown of factorization is discussed. Cross section estimates are given from a simpl...
متن کاملOn factorization, quark counting and vector dominance
Using an eikonal structure for the scattering amplitude, Block and Kaidalov[1] have derived factorization theorems for nucleon-nucleon, γp and γγ scattering at high energies, using only some very general assumptions. We present here an analysis giving experimental confirmation for factorization of cross sections, nuclear slope parameters B and ρ-values (ratio of real to imaginary portion of for...
متن کاملHeavy Quark Photoproduction in k ⊥ - Factorization Approach
We investigate the heavy quark photoproduction based on the k ⊥-factorization approach, focusing on the results from the saturation model. The deviations in the results using the unintegrated gluon distribution considering the saturation model and the derivative of the collinear gluon distribution are analysed. Total cross sections and p T distributions are analysed in detail, setting the devia...
