NNLO QCD corrections to unpolarized and polarized SIDIS
Saurav Goyal, Roman N. Lee, Sven-Olaf Moch +3
The semi-inclusive deep-inelastic scattering (SIDIS) process requires the presence of an identified hadron H in the final state, which arises from the scattering of a lepton wit…
Next-to-Next-to-Leading Order QCD Corrections to Polarized Semi-Inclusive Deep-Inelastic Scattering
Saurav Goyal, Roman N. Lee, Sven-Olaf Moch +3
Polarized semi-inclusive deep-inelastic scattering (SIDIS) is a key process in the quest for a resolution of the proton spin puzzle. We present the complete results for the polariz…
NNLO QCDQED corrections to unpolarized and polarized SIDIS
Saurav Goyal, Roman N. Lee, Sven-Olaf Moch +2
We present the first computation of next-to-next-to-leading order (NNLO) pure QED and mixed QCDQED corrections to unpolarized and polarized semi-inclusive deep-inelastic s…
Monodromy of multiloop integrals in dimensions
Roman N. Lee, Andrei A. Pomeransky
We consider the monodromy group of the differential systems for multiloop integrals. We describe a simple heuristic method to obtain the monodromy matrices as functions of space-ti…
NNLO phase-space integrals for semi-inclusive deep-inelastic scattering
Taushif Ahmed, Saurav Goyal, Syed Mehedi Hasan +6
We evaluate the phase-space integrals that arise in double real emission diagrams for semi-inclusive deep-inelastic scattering at next-to-next-to-leading order (NNLO) in QCD. Utili…
