  Abstract:
We present the results of a global fit to data from different hadronization processes such as single-inclusive electron-positron annihilation and semi-inclusive deep inelastic scattering to calculate pion and kaon fragmentation functions. We perform an improvement to the pion and kaon fragmentation functions at next-to-leading order (NLO), by including recent single-inclusive electron-positron annihilation data from BaBar and Belle at Q = 10.54 GeV and Q = 10.52 GeV, respectively. Our main purpose is to show how much imposing of these new data in our analysis improves the fragmentation functions of pion and kaon at NLO.
