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…
Calculational Techniques in Particle Theory
Lorenzo Tancredi
In this contribution, I review some of the latest advances in calculational techniques in theoretical particle physics. I focus, in particular, on their application to the calculat…
Analytic results for two-loop planar master integrals for Bhabha scattering
Claude Duhr, Vladimir A. Smirnov, Lorenzo Tancredi
We analytically evaluate the master integrals for the second type of planar contributions to the massive two-loop Bhabha scattering in QED using differential equa- tions with canon…
Two-loop leading colour QCD corrections to and
Bakul Agarwal, Federico Buccioni, Andreas von Manteuffel +1
We present the leading colour and light fermionic planar two-loop corrections for the production of two photons and a jet in the quark-antiquark and quark-gluon channels. In partic…
Tensor decomposition for bosonic and fermionic scattering amplitudes
Tiziano Peraro, Lorenzo Tancredi
In this paper, we elaborate on a method to decompose multiloop multileg scattering amplitudes into Lorentz-invariant form factors, which exploits the simplifications that arise fro…
Di-photon amplitudes in three-loop Quantum Chromodynamics
Fabrizio Caola, Andreas von Manteuffel, Lorenzo Tancredi
We consider the three-loop scattering amplitudes for the production of a pair of photons in quark-antiquark annihilation in Quantum Chromodynamics (QCD). We use suitably defined pr…
