Abstract:
We discuss how the experimental information from longitudinal single-spin asymmetries for W ± boson production in polarised proton-proton collisions can be included in a polarised parton determination by Bayesian reweighting of a Monte Carlo set of polarised PDF replicas. We explicitly construct a prior ensemble of polarised parton distributions using available fits to inclusive and semiinclusive DIS data and we discuss the potential impact of existing and future RHIC measurements on it.
