Meson twist-4 parton distributions in terms of twist-2 distribution amplitudes at large Nc
N. -Y. Lee, P. V. Pobylitsa, M. V. Polyakov +1
We show that in the large N_c limit four-quark twist-4 distributions in the pion can be expressed in terms of twist-2 pion distribution amplitude. This allows us to compute the iso…
Gluon and quark distributions in large N_c QCD: theory vs. phenomenology
A. V. Efremov, K. Goeke, P. V. Pobylitsa
We present the QCD analysis of the behavior of quark and gluon distributions in the limit of a large number of colors N_c. We show that the results agree qualitatively with the phe…
New positivity bounds on polarized parton distributions in multicolored QCD
P. V. Pobylitsa, M. V. Polyakov
We derive new positivity bounds on spin-dependent parton distributions in multicolored QCD. They are stronger than Soffer inequality. We check that the new inequalities are stable…
Polarized antiquark distributions from chiral quark-soliton model: summary of the results
K. Goeke, P. V. Pobylitsa, M. V. Polyakov +1
In these short notes we present a parametrization of the results obtained in the chiral quark-soliton model for polarized antiquark distributions , and …
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…
