Pion wave function from the instanton vacuum model
V. Yu. Petrov, P. V. Pobylitsa
The pion wave function is computed in the low energy effective theory inspired by the instanton vacuum model. The resultat is numerically rather close to the asymptotical wave func…
Off-forward quark distributions of the nucleon in the large N_c limit
V. Yu. Petrov, P. V. Pobylitsa, M. V. Polyakov +3
We study the off-forward quark distributions (OFQD's) in the chiral quark-soliton model of the nucleon. This model is based on the large-N_c picture of the nucleon as a soliton of…
Unpolarized and polarized quark distributions in the large-Nc limit
D. I. Diakonov, V. Yu. Petrov, P. V. Pobylitsa +2
The isosinglet unpolarized and isovector polarized twist-2 quark distributions of the nucleon at low normalization point are calculated in the large-Nc limit. The nucleon is descri…
