OPE analysis of the nucleon scattering tensor including weak interaction and finite mass effects
M. Maul, B. Ehrnsperger, E. Stein +1
We perform a systematic operator product expansion of the most general form of the nucleon scattering tensor including electro-magnetic and weak interaction processes. Fin…

The connection between single transverse spin asymmetries and the second moment of
B. Ehrnsperger, A. Schaefer, W. Greiner +1
We point out that the size of the photon single spin asymmetry in high--energy proton proton collisions with one transversely polarized proton can be related to , the twis…

OPE analysis for polarized deep inelastic scattering
B. Ehrnsperger, L. Mankiewicz, A. Schäfer
We present an explicit OPE analysis for the first moment of up to order . This result allows to calculate power corrections to the Bjorken and Ellis--Jaffe sum rules…
