Description
The chirally-odd twist-3 nucleon distribution ea(x) is studied in the large-Nc limit in the framework of the chiral quark-soliton model at a low normalization point of about 0.6 GeV. The remarkable result is that in the model ea(x) contains a δ-function-type singularity at x=0. The regular part of ea(x) is found to be sizable at the low scale of the model and in qualitative agreement with bag model calculations
