A determination of the spin content of the proton with faithful uncertainty estimation
Proceedings of XVIII International Workshop on Deep-Inelastic Scattering and Related Subjects — PoS(DIS 2010)
We review recent progress towards a determination of a set of polarized parton distributions from a global set of deep-inelastic scattering data based on the NNPDF methodology, in analogy with the unpolarized case. This method is designed to provide a faithful and statistically sound representation of parton distributions and their uncertainties. We show how the FastKernel method provides a fast and accurate method for solving the polarized DGLAP equations. We discuss the polarized PDFdoi:10.22323/1.106.0244 fatcat:tdqv3vybpjdbrcdtfdlhiob464
