We study the contribution of the twist-3 fragmentation function to the single-transverse spin asymmetry in semi-inclusive deep inelastic scattering within the framework of the collinear factorization. Making use of the Ward-Takahashi identity in QCD, we establish the formalism in the Feynman gauge to calculate the non-pole contribution of the twist-3 fragmentation function to the asymmetry and derive the complete cross-section formula in the leading order QCD perturbation theory. The obtained twist-3 hadronic tensor is shown to satisfy the electromagnetic gauge-invariance. The behavior in the small transverse- momentum region for the five structure functions is also given.

Single spin asymmetry in forward $pA$ collisions from Pomeron-Odderon interference
A new Pomeron-Odderon interference term in the hybrid CGC framework yields a percent-level transverse single spin asymmetry in forward pA collisions, with a characteristic sign-changing node at the saturation scale.
