Chirally-odd twist-3 distribution function ea(x) in the chiral quark-soliton model -: art. no. 114010

The chirally-odd twist-3 nucleon distribution e(a)(x) is studied in the large-N-c 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 e(a)(x) contains a delta-function-type singularity at x=0. The regular part of e(a)(x) is found to be sizable at the low scale of the model and in qualitative agreement with bag model calculations.
