Description
I present a first determination of a set of collinear fragmentation functions of charged pions based on the NNDPF methodology. The determination includes a wide set of single-inclusive annihilation data and is performed up to next-to-next-to-leading order accuracy in perturbative quantum chromodynamics. I discuss the results of the fits, highlighting the quality of the description of the data, their stability upon the inclusion of higher-order corrections, and some of their implications in the investigation of the spin structure of the nucleon.
