This is an old revision of this page, as edited by 184.153.19.128 (talk) at 17:40, 3 December 2018 (Rewritten paragraph. The previous content was wrong on several counts. E.g. Fragmentation functions do not exist solely for mesons, they only have a probabilistic interpretation at leading order etc. Also added a 'standard' reference in a refereed journal.). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

In a sufficiently hard interaction between particles, the cross section can be factorized into parton distribution functions (PDFs), the hard scattering part, and fragmentation functions. The fragmentation functions, as are the PDFs, are non-perturbative functions describing the production of a given observed final state. In a leading order picture, it can be interpreted as the probability that the observed final state originates from a given quark or gluon[1].
