Abstract:
We present a first preliminary determination of a set of collinear fragmentation func-
tions of charged pions based on the NNPDF methodology. This determination is based on a wide
set of single-inclusive annihilation data, including the most recent and precise measurements from
B-factory experiments. Our analysis is performed at leading, next-to-leading and next-to-next-
to-leading order in quantum chromodynamics. We discuss the result of our fits, highlighting the
quality of their description of the data and their stability upon inclusion of higher-order corrections.
