Scale dependence of twist-three contributions to single spin asymmetries — •Björn Pirnay1, Vladimir Braun1, and Alexander Manashov1,21Institut für Theoretische Physik, Universität Regensburg — 2Department of Theoretical Physics, St. Petersburg State University

We reexamine the scale dependence of twist-three correlation functions relevant for the single transverse spin asymmetry in the framework of collinear factorization. Evolution equations are derived for both the flavor-nonsinglet and flavor-singlet distributions and arbitrary parton momenta. Our results do not agree with the recent calculations of the evolution in the limit of vanishing gluon momentum. Possible sources for this discrepancy are identified.
