Infrared divergences in the perturbative expansion of gauge theory amplitudes and cross
sections have been a focus of theoretical investigations for almost a century. New insights …

We review in a pedagogical way the method of differential equations for the evaluation of D-
dimensionally regulated Feynman integrals. After dealing with the general features of the …

We review the Hopf algebra of the multiple polylogarithms and the symbol map, as well as
the construction of single valued multiple polylogarithms and discuss an algorithm for finding …

Feynman integrals are indispensable for precision calculations in quantum field theory. They
occur as soon as one goes beyond the leading order in perturbative quantum field theory …

We present high-accuracy QCD predictions for the transverse-momentum (q T) distribution
and fiducial cross sections of Drell–Yan lepton pairs produced in hadronic collisions. At …

A bstract We present the complete formula for the cusp anomalous dimension at four loops
in QCD and in maximally supersymmetric Yang-Mills. In the latter theory it is given …

In this work we report on a new version of FeynCalc, a Mathematica package widely used in
the particle physics community for manipulating quantum field theoretical expressions and …

We calculate the unpolarized and polarized three–loop anomalous dimensions and splitting
functions P NS+, P NS− and P NS s in QCD in the MS‾ scheme by using the traditional …

A bstract We compute the next-to-next-to-leading order QCD correction to the total inclusive
top pair production cross-section in the reaction\(qg\to t\overline {t}+ X\). We find …

A bstract We use\(\mathcal {N}\)= 8 supergravity as a toy model for understanding the
dynamics of black hole binary systems via the scattering amplitudes approach. We compute …
