Summary
The paper discusses the computation of next-to-next-to-leading order (NNLO) QCD corrections to unpolarized and polarized semi-inclusive deep-inelastic scattering (SIDIS). The corrections are significant and crucial for reducing the dependence on the renormalization and factorization scales.
Highlights
- NNLO QCD corrections to SIDIS are computed for the first time.
- The corrections are significant and reduce the scale dependence.
- The results are obtained using the Larin's scheme for γ5 in d=4+ε dimensions.
- The computation involves 20 master integrals, which are evaluated using various techniques.
- The results are checked against the known results for the threshold expansion.
- The corrections are important for the extraction of parton distribution functions (PDFs) and fragmentation functions (FFs).
- The results are applicable to the Electron-Ion Collider (EIC) experiments.
Key Insights
- The NNLO QCD corrections to SIDIS are significant and reduce the scale dependence, which is crucial for the precise extraction of PDFs and FFs.
- The computation of NNLO corrections involves the evaluation of 20 master integrals, which requires advanced techniques and significant computational resources.
- The results are obtained using the Larin's scheme for γ5 in d=4+ε dimensions, which is a widely used scheme for computing higher-order QCD corrections.
- The corrections are important for the EIC experiments, which aim to study the structure of hadrons and nuclei with high precision.
- The NNLO corrections are also important for the study of spin-dependent PDFs, which are crucial for understanding the spin structure of hadrons.
- The results demonstrate the importance of higher-order QCD corrections for the precise extraction of PDFs and FFs, which are essential for understanding the structure of hadrons and nuclei.
- The computation of NNLO corrections to SIDIS is a significant step forward in the field of particle physics, as it provides a new level of precision for the extraction of PDFs and FFs.
