We show that quark operators of twist 3 contributing to the polarized nucleon structure function g2tw.3(x, Q2) decouple from the evolution equation for the quark-gluon operators of the same twist in two important limits,Nc→∞ and n→∞ (Nc is the number of colours and n refers to the nth moment of g2). The anomalous dimensions for the quark operators turn out to be always the lowest ones in the ...
