The obtained parametrization is in good agreement with all data sets analyzed and can be utilized, for instance, in future studies of double-spin asymmetries for single-inclusive eta production. The Lagrange multiplier technique is used to estimate the uncertainties of the fragmentation functions and to assess the role of the different data sets in constraining them.", "revisions": [ { "version": "v2", "updated": "2010-10-05T18:12:07.000Z" } ], "analyses": { "subjects": [ "13.85.Ni", "13.87.Fh", "12.38.Bx" ], "keywords": [ "fragmentation functions", "eta mesons", "global analysis", "data sets", "lagrange multiplier technique" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2011, "month": "Feb", "volume": 83, "number": 3, "pages": "034002" }, "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "inspire": 871259, "adsabs": "2011PhRvD..83c4002A" } } }
