Identified Hadron Production in Deeply Inelastic Neutrino-Nucleon Scattering

The production of identified hadrons in semi-inclusive deep-inelastic scattering (SIDIS) is sensitive to parton distribution functions and hadron fragmentation functions. Neutrino-induced SIDIS processes probe combinations of these functions different from their charged-lepton-induced counterparts. We compute charged pion production in (anti-)neutrino induced SIDIS up to second order in perturbative QCD and compare our predictions to precise legacy fixed-target data. We demonstrate the high sensitivity of these data on the parametrization of the fragmentation functions and discuss future SIDIS probes at the LHC Forward Physics Facility.
