HyperFORM -- a FORM package for parametric integration with hyperlogarithms
Adam Kardos, Sven-Olaf Moch, Oliver Schnetz
HyperFORM brings the parametric integration of hyperlogarithms, weighted by rational prefactors, into the symbolic-manipulation system FORM. It ports the capabilities of Erik Panze…
HyperFORM -- a FORM package for parametric integration with hyperlogarithms
Adam Kardos, Sven-Olaf Moch, Oliver Schnetz
We present an implementation of algorithms for the symbolic integration of hyperlogarithms multiplied by rational functions in the computer algebra system FORM. This implementation…
Heavy-quark production in deep-inelastic scattering -- Mellin moments of structure functions
Marco Klann, Sven-Olaf Moch, Kay Schönwald
We compute Mellin moments of the heavy-quark structure functions in deep-inelastic scattering at next-to-leading order in quantum chromodynamics, retaining their full dependence on…
Soft and Jet functions for SCET at four loops in QCD
Saurav Goyal, Sven-Olaf Moch, Vaibhav Pathak +1
Soft-Collinear Effective Theory is a framework for systematically organizing and resumming the logarithmic contributions that occur in high-energy reactions. It provides a factoriz…
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…
