The constraints on the non-singlet polarised parton densities from the infrared-renormalon model
PACS: 11.15.Tx, 12.88.+e, 13.85.Hd
Abstract
Using the infrared-renormalon approach, we obtain the constraints on the next-to-leading order non-singlet polarised parton densities. The advocated feature follows from the consideration of the effect revealed in the process of the next-to-leading order fits to the data for the assymetry of polarised lepton-nucleon scattering which result in the approximate nullification of the 1/Q2-correction to A1N(x,Q2).
