Abstract

We examine the large-x QCD evolution of the twist-three gluonic-pole strength defining an effective T-odd Sivers function, where evolution of the T-even transverse-spin DIS structure function g₂ is multiplicative. The result corresponds to a colour-factor modified spin-averaged twist-two evolution.
