Single-valued representation of unpolarized and polarized semi-inclusive deep inelastic scattering at next-to-next-to-leading order
Juliane Haug, Fabian Wunder
We revisit the recently published analytic results for unpolarized and polarized semi-inclusive deep inelastic scattering (SIDIS) at next-to-next-to-leading order (NNLO) in QCD. Th…
Angular integrals with three denominators via IBP, mass reduction, dimensional shift, and differential equations
Juliane Haug, Fabian Wunder
Angular integrals arise in a wide range of perturbative quantum field theory calculations. In this work we investigate angular integrals with three denominators in $d=4-2\varepsilo…
On multi-propagator angular integrals
Juliane Haug, Vladimir A. Smirnov, Fabian Wunder
We study multi-propagator angular integrals, a class of phase-space integrals relevant to processes with multiple observed final states and a test-bed for transferring loop-integra…
A semi-analytical -space solution for parton evolution -- Application to non-singlet and singlet DGLAP equation
Juliane Haug, Oliver Schüle, Fabian Wunder
We present a novel semi-analytical method for parton evolution. It is based on constructing a family of analytic functions spanning -space which is closed under the considered e…
