The ice cone family and iterated integrals for Calabi-Yau varieties
Claude Duhr, Albrecht Klemm, Christoph Nega +1
We present for the first time fully analytic results for multi-loop equal-mass ice cone graphs in two dimensions. By analysing the leading singularities of these integrals, we find…
Signal-background interference effects in Higgs-mediated diphoton production beyond NLO
Piotr Bargiela, Federico Buccioni, Fabrizio Caola +3
In this paper we consider signal-background interference effects in Higgs-mediated diphoton production at the LHC. After reviewing earlier works that show how to use these effects…
Beam functions for -jettiness at NLO in perturbative QCD
Daniel Baranowski, Arnd Behring, Kirill Melnikov +2
We present a calculation of all matching coefficients for -jettiness beam functions at next-to-next-to-next-to-leading order (NLO) in perturbative quantum chromodynamics (QC…
Two-loop QCD corrections to the helicity amplitudes with axial-vector couplings
Thomas Gehrmann, Tiziano Peraro, Lorenzo Tancredi
We compute the two-loop corrections to the helicity amplitudes for the coupling of a massive vector boson to a massless quark-antiquark pair and a gluon, accounting for vector and…
Three-loop helicity amplitudes for quark-gluon scattering in QCD
Fabrizio Caola, Amlan Chakraborty, Giulio Gambuti +2
We compute the three-loop helicity amplitudes for and its crossed partonic channels, in massless QCD. Our analytical results provide a non-trivial check of the co…
Functions Beyond Multiple Polylogarithms for Precision Collider Physics
Jacob L. Bourjaily, Johannes Broedel, Ekta Chaubey +14
Feynman diagrams constitute one of the essential ingredients for making precision predictions for collider experiments. Yet, while the simplest Feynman diagrams can be evaluated in…
