A determination of the fragmentation functions of pions, kaons, and protons with faithful uncertainties
NNFF1.0 is the first determination of the fragmentation functions of pions, kaons and protons based on the NNPDF methodology. It is performed at leading, next-to-leading and next-to-next-to-leading order and includes a comprehensive set of single-inclusive electron-positron annihilation data. With NNPDF3.1 and NNPDFpol1.1, NNFF1.0 makes unpolarized and polarized PDFs and fragmentation functions available from a common fitting framework for the first time.
