Polarized parton distributions and non-leading reggeons
R. Kirschner
Abstract
The small x behaviour of polarized parton distributions is related to non-leading reggeons in the framework of the high-energy effective action. Double-logarithmic contributions to the reggeon interaction beyond the ones included in the GLAP equation are encountered in all polarized parton distributions. The transversity distributions of quarks and gluons behave similar at small x. Contribution to the spin workshop at DESY-Zeuthen, September 1997.
