Chiral-Odd Twist-3 Distribution Function

M. Wakamatsu, Y. Ohnishi

We clarify the nonperturbative origin of the -function singularity at in the chiral-odd twist-3 distribution function of the nucleon. We also compare a theoretica…

The nonperturbative origin of delta-function singularity in the chirally-odd twist-3 distribution function e(x)

M. Wakamatsu, Y. Ohnishi

We analytically prove that the existence of the delta-function singularity in the chirally-odd twist-3 distribution of the nucleon is inseparably connected with the nonvanis…
