Single-spin asymmetry from pomeron-odderon interference
M. Jarvinen
Abstract
The transverse single-spin asymmetry AN observed in high energy proton-proton collisions p p pi X has been found to increase with the momentum fraction xF of the pion up to the largest measured xF 0.8, where AN 40%. We consider the possibility that the asymmetry is due to a non-perturbatively generated spin-flip coupling in soft rescattering on the target proton. We demonstrate using perturbation theory that a non-vanishing asymmetry can be generated through interference between exchanges of even and odd charge conjugation provided both helicity flip and non-flip couplings contribute. Pomeron and odderon exchange can thus explain the energy independence of the asymmetry and predicts that the asymmetry should persist in events with large rapidity gaps.
