Titre |
Semi-inclusive deep-inelastic scattering at NNLO in QCD |
|
Résumé |
Semi-inclusive hadron production processes in deep-inelastic lepton-nucleon scattering (SIDIS) are
important probes of the fragmentation dynamics of quarks into hadrons. Moreover, longitudinally
polarized SIDIS is a powerful tool for resolving the quark flavor decomposition of the proton's spin
structure. In this talk, I will present the recent calculation of the full next-to-next-to-leading order (NNLO)
QCD corrections to the unpolarized and longitudinally polarized SIDIS coefficient functions. I will comment
on the numerical impact of these corrections in different kinematical regions and on the usage of these
predictions in the context of global fits of parton distribution functions and fragmentation functions. |
