Photoproduction on polarized quarks in QCD

Creators

Description

A general form of the angular dependence in the process γq → Xq with an arbitrary polarized initial particles is obtained. In the case of the unpolarized final quark this dependence is determined by the four structure functions, which are calculated for processes γq → Q anti Qq and γq → gq. It is shown that possible breaking of T-invariance in gQ anti Q vertex do not lead to new angle dependences
