Abstract

We calculate the chiral odd quark distributions and the corresponding structure functions (Formula presented) and (Formula presented) within the Nambu–Jona-Lasinio chiral soliton model for the nucleon. The (Formula presented) evolution of the twist-2 contributions is performed according to the standard GLAP formalism while the twist-3 piece (Formula presented) is evolved according to the large (Formula presented) scheme. We carry out a comparison between the chiral odd structure functions of the proton and the neutron. At the low model scale (Formula presented) we find that the leading twist effective quark distributions (Formula presented) (Formula presented) and (Formula presented) satisfy Soffer’s inequality for both quark flavors (Formula presented).
