We present a determination of fragmentation functions (FFs) for the octet baryon Ξ−/ˉΞ+ from data for single inclusive electron-positron annihilation. Our parametrization in this QCD analysis is provided in terms of a Neural Network (NN).
We determine fragmentation functions for Ξ−/ˉΞ+ at next-to-leading order and for the first time at next-to-next-to-leading order in perturbative QCD. We discuss the improvement of higher-order QCD corrections, the quality of fit, and the comparison of our theoretical results with the fitted datasets. As an application of our new set of fragmentation functions, named {\tt SHKS22}, we present predictions for Ξ−/ˉΞ+ baryon production in proton-proton collisions at the LHC experiments.
