The four-loop non-singlet splitting functions in QCD
Thomas Gehrmann, Andreas von Manteuffel, Vasily Sotnikov +1
The scale evolution of parton distributions is governed by splitting functions. We compute the four-loop splitting functions in perturbative QCD that control the evolution of quark…
The Single-Mass Variable Flavor Number Scheme at Three-Loop Order
J. Ablinger, A. Behring, J. Blümlein +4
The matching relations in the unpolarized and polarized variable flavor number scheme at three-loop order are presented in the single-mass case. They describe the process of massiv…
Leading Twist-Two Gauge-Variant Counterterms
Thomas Gehrmann, Andreas von Manteuffel, Tong-Zhi Yang
Anomalous dimensions of twist-two operators govern the scale evolution of parton distribution functions. For off-shell external states, the physical twist-two operators mix with un…
Multiple polylogarithms with algebraic arguments and the two-loop EW-QCD Drell-Yan master integrals
Matthias Heller, Andreas von Manteuffel, Robert M. Schabinger
We consider Feynman integrals with algebraic leading singularities and total differentials in form. We show for the first time that it is possible to evaluate in…
Master Integrals for the two-loop, non-planar QCD corrections to top-quark pair production in the quark-annihilation channel
Matteo Becchetti, Roberto Bonciani, Valerio Casconi +3
We present the analytic calculation of the Master Integrals for the two-loop, non-planar topologies that enter the calculation of the amplitude for top-quark pair hadroproduction i…
Heavy flavour corrections to polarised and unpolarised deep-inelastic scattering at 3-loop order
Jakob Ablinger, Arnd Behring, Johannes Blümlein +6
We report on progress in the calculation of 3-loop corrections to the deep-inelastic structure functions from massive quarks in the asymptotic region of large momentum transfer $Q^…
