Helicity skewed quark distributions of the nucleon and chiral symmetry
2000
Physical Review D, Particles and fields
We compute the helicity skewed quark distributions H and E in the chiral quark-soliton model of the nucleon. This model emphasizes correctly the role of spontaneously broken chiral symmetry in structure of nucleon. It is based on the large-N_c picture of the nucleon as a soliton of the effective chiral lagrangian and allows to calculate the leading twist quark- and antiquark distributions at a low normalization point. We discuss the role of chiral symmetry in the helicity skewed quark
