Deuteron Spin Structure Functions at Small Bjorken - x †
We investigate polarized deuteron structure functions at small values of the Bjorken variable, x < 0.1. In this region contributions from the coherent interaction of diffractively excited hadronic states with both nucleons become important. A proper treatment of this process requires an extension of the Glauber-Gribov multiple scattering theory to include spin degrees of freedom. In the kinemat...
متن کاملPolarized deuteron structure functions at small x ∗
We investigate shadowing corrections to the polarized deuteron structure functions g d 1 and b 1. In the kinematic domain of current fixed target experiments we observe that shadowing effects in g d 1 are approximately twice as large as for the unpolarized structure function F d 2. Furthermore, we find that b 1 is surprisingly large at x < 0.1 and receives dominant contributions from coherent d...
متن کاملDeeply virtual vector meson electroproduction at small Bjorken-x
It is reported on an analysis of vector meson electroproduction at small Bjorken-x (xBj) within the handbag approach. Using a model for the generalized parton distributions (GPDs) and calculating the partonic subprocess, electroproduction off gluons, within the modified perturbative approach, cross sections and spin density matrix elements (SDME) are evaluated. The numerical results of this ana...
متن کاملQCD Evolution of Structure Functions at Small x
The status of the resummation of small x contributions to the unpolarized and polarized deep inelastic structure functions is reviewed. Lecture notes to appear in the Proceedings of the Ringberg Workshop ”New Trends in HERA Physics 1999”, eds. G. Grindhammer, B. Kniehl, and G. Kramer (Springer, Berlin 1999).
متن کاملThe Evolution of Unpolarized Singlet Structure Functions at Small x
A systematic study is performed of the impact of the various resummed small-x contributions to the anomalous dimensions and coefficient functions on the evolution of unpolarized structure functions in deep-inelastic scattering. The proton structure functions F p 2 and F p L as well as the photon structure function F γ 2 are considered together with the corresponding parton densities. The genera...
