Recent Developments in Perturbative Qcd: Q 2 Evolution of Chiral-odd Distributions
نویسنده
چکیده
After reviewing QCD definitions of the chiral-odd spin-dependent parton distributions h1(x,Q) and hL(x,Q 2), I will summarize the main feature of the recent two results in perturbative QCD: (i) Next-to-leading order Q2 evolution of h1(x,Q). (ii) Leading order Q2 evolution of the twist-3 distribution hL(x,Q 2) and the universal simplification of the Q2 evolution of all the twist-3 distributions in the large Nc limit.

From Diphoton GDAs and Photon GPDs to the chiral odd Photon DA
The photon is a very interesting object for QCD studies since it has both a pointlike coupling to quarks, which yields a perturbative part of photons wave function, and a non-perturbative coupling related to the magnetic susceptibility of the QCD vacuum and which builds its chiral-odd twist-2 distribution amplitude. The first feature allows us to compute the photon anomalous generalized parton ...
متن کاملProbing the Perturbative NLO Parton Evolution in the Small–x Region
A dedicated test of the perturbative QCD NLO parton evolution in the very small–x region is performed. We find a good agreement with recent precision HERA–data for F p 2 (x,Q), as well as with the present determination of the curvature of F p 2 . Characteristically, perturbative QCD evolutions result in a positive curvature which increases as x decreases. Future precision measurements in the ve...

Several topics in hadron physics at different scales of resolution are discussed. First, deep-inelastic scattering from nucleons and nuclei is viewed in a light-cone coordinate space picture. Then the smooth transition from parton to hadron degrees of freedom is demonstrated by analysing generalized Q-dependent polarizabilities of the nucleon. Turning to low energy QCD we summarize recent devel...
متن کاملNucleon parton distributions in the large N c limit ∗
We review recent progress in calculating the twist–2 parton distribution functions (PDF's) at a low normalization point in the large–N c limit, where the nucleon can be described as a soliton of the effective chiral lagrangian. This field–theoretic approach preserves all general requirements on the PDF's (positivity, normalization etc.). In particular, it allows to calculate the polarized and u...
متن کاملLight Vector Meson Photoproduction at High |t|
We have studied in perturbative QCD all independent helicity amplitudes describing the photoproduction of light vector mesons at large t. We found a new hard production mechanism which is related to the possibility for a real photon to fluctuate into a massless q ¯ q pair in a chiral-odd spin configuration. Each helicity amplitude is given as a sum of chiral-even contribution (when the heliciti...
