The 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...
متن کاملThe Small-x Evolution of Unpolarized and Polarized Structure Functions
A brief overview is presented of recent developments concerning resummed small-x evolution, based upon the renormalization group equation. The non-singlet and singlet structure functions are discussed for both polarized and unpolarized deep-inelastic scattering. Quantitative results are displayed and uncertainties from uncalculated subleading terms are discussed. ∗ Based on an invited talk pres...
متن کاملThe Evolution of Unpolarized and Polarized Structure Functions at Small x∗
A survey is given of recent developments on the resummed small-x evolution, in a framework based on the renormalization group equation, of non–singlet and singlet structure functions in both unpolarized and polarized deep–inelastic scattering. The available resummed anomalous dimensions are discussed for all these cases, and the most important analytic and numerical results are compiled. The qu...
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 کاملUnpolarized Structure Functions
Over the past decade measurements of unpolarized structure functions with unprecedented precision have significantly advanced our knowledge of nucleon structure. These have for the first time allowed quantitative tests of the phenomenon of quark-hadron duality, and provided a deeper understanding of the transition from hadron to quark degrees of freedom in inclusive scattering. Dedicated Rosenb...
