摘要

In order to examine the validity of Wandzura-Wilczek relation for the polarized DIS structure function g₂(x, Q²), we use the light-front time-ordering pQCD to calculate g₂(x, Q²) at order α_s on a quark target. We find that the study of the transverse polarized structure function in pQCD is only meaningful if we begin with massive quarks. The result shows that the Wandzura-Wilczek relation for g₂(x, Q²) is strongly violated by the quark mass in pQCD.
