The precision frontier in collider physics is being pushed at impressive speed, from both the
experimental and the theoretical side. The aim of this review is to give an overview of recent …

We give a comprehensive review of recent developments on using the pure spinor
formalism to compute massless superstring scattering amplitudes at tree level. The main …

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 …

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 provide algorithms for symbolic integration of hyperlogarithms multiplied by rational
functions, which also include multiple polylogarithms when their arguments are rational …

Feynman diagrams constitute one of the essential ingredients for making precision
predictions for collider experiments. Yet, while the simplest Feynman diagrams can be …

We present the perturbative renormalization group functions of O (n)-symmetric ϕ 4 theory in
4-2 ϵ dimensions to the sixth loop order in the minimal subtraction scheme. In addition, we …

A bstract We obtain generalised power series expansions for a family of planar two-loop
master integrals relevant for the QCD corrections to Higgs+ jet production, with phys-ical …

We present a new computer program, feyntrop, which uses the tropical geometric approach
to evaluate Feynman integrals numerically. In order to apply this approach in the physical …

A bstract We use the numerical bootstrap to study conformal line defects with O (2) global
symmetry. Our results are very general and capture in particular conformal line defects …
