Description
The production of identified hadrons in lepton-nucleon scattering (semi-inclusive deep inelastic scattering, SIDIS) allows for detailed analyses of parton distributions and fragmentation functions.
For polarised nucleons, the spin structure of the nucleon target can be proved to a more detailed level than through fully inclusive processes.
We present our calculations of the full set of next-to-next-to leading order (NNLO) QCD corrections to polarised and unpolarised neutral and charged current SIDIS coefficient functions.
We study the numerical impact of our results with a focus on the kinematical settings of the future Electron-Ion Collider (EIC).
We further highlight the impact that our results will have on the extraction of fragmentation functions from so-far ignored neutrino-induced SIDIS data.
Our results enable for the first time a consistent treatment of charged and neutral current induced hadron fragmentation processes in DIS at NNLO in QCD.
