Constraints on polarized parton distributions from open charm and W production data / E. Nocera. - In: POS PROCEEDINGS OF SCIENCE. - ISSN 1824-8039. - 2013:(2013 Jun 29), pp. 211.1-211.6. (Intervento presentato al 21. convegno International workshop on deep-inelastic scattering and related subjects (DIS) tenutosi a Marseilles nel 2013).
Abstract:
We study the impact of new open charm muoproduction data from COMPASS and
preliminary W 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.
