Constraints on polarized parton distributions from open charm and W production data

Contributo in Atti di convegno
Data di Pubblicazione:
2013
Abstract:
We study the impact of new open charm muoproduction data from COMPASS and preliminary $W^\pm$ production data from STAR on NNPDFpol1.0, the first unbiased set of polarized parton distributions recently delivered by the NNPDF Collaboration and based on inclusive Deep-Inelastic Scattering data only. The information contained in the new data sets is incorporated in our Monte Carlo parton determination via Bayesian reweighting, a method based on statistical inference which avoids the need for a global refitting. We explicitly show to which extent COMPASS and STAR data can improve our knowledge of gluon and antiquark polarized parton distributions respectively.
