Baryon wave function: Large-Nc QCD and lessons from models
P. V. Pobylitsa
The structure of the 1/Nc expansion for the baryon distribution amplitude in QCD is tested using quark models. Earlier conjectures about this structure based on the evolution equat…
Transverse-momentum dependent parton distributions in large-Nc QCD
P. V. Pobylitsa
The transverse-momentum dependent quark distributions are studied in the limit of the large number of colors Nc. The leading orders of Nc are determined for all twist-2 distributio…
T-odd quark distributions: QCD versus chiral models
P. V. Pobylitsa
The T-odd quark distrbutions are shown to vanish in the chiral sigma model in contrast to the opposite widespread opinion. This failure of the chiral sigma model is a feature of th…
Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena
M. J. Amarian, V. M. Braun, S. J. Brodsky +28
These are the mini-proceedings of the workshop ``Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena" held at the Physikzentrum Bad Honnef from July 15 to 19, 2002. Every a…
Quark distribution functions in the chiral quark-soliton model: cancellation of quantum anomalies
K. Goeke, P. V. Pobylitsa, M. V. Polyakov +2
In the framework of the chiral quark-soliton model of the nucleon we investigate the properties of the polarized quark distribution. In particular we analyse the so called anomalou…
Flavor asymmetry of polarized and unpolarized sea quark distributions in the large-N_c limit
B. Dressler, K. Goeke, P. V. Pobylitsa +3
We summarize recent attempts to calculate the flavor asymmetry of the nucleon's sea quark distributions in the large- limit, where the nucleon can be described as a soliton of…
