Parton interactions in the Bjorken limit of QCD

We consider the Bjorken limit in the framework of the eectiv e action approach and discuss its similarities to the Regge limit. The proposed eectiv e action allows for a rather simple calculation of the known evolution kernels. We represent the result in terms of two-parton interaction operators involving gluon and quark operators depending on light-ray position and helicity and analyze their symmetry properties.
