Global analysis of fragmentation functions for pions and kaons and their uncertainties
Global analysis of fragmentation functions for pions and kaons and their uncertainties
We present new sets of pion and kaon fragmentation functions obtained in next-to-leading order combined analyses of single-inclusive hadron production in electron-positron annihilation, proton-proton collisions, and deep-inelastic lepton-proton scattering with either pions or kaons identified in the final state. At variance with all previous fits, the present analyses take into …
