Description
In this contribution, I will present a determination of unpolarised charged pion and kaon fragmentation functions (FFs) from a set of single-inclusive electron-positron annihilation (SIA) and lepton-nucleon semi-inclusive deep-inelastic scattering (SIDIS) data. The determination is carried out in a framework that combines a neural-network parametrisation of fragmentation functions with a Monte Carlo representation of their uncertainties. It includes exact next-to-next-to-leading (NNLO) order QCD corrections to SIA and approximated NNLO corrections to SIDIS. In view of the recent computation of exact NNLO corrections to SIDIS, I will also comment on their impact on FFs.
