Compact Two-Loop QCD Corrections for Production in Proton Collisions
Giuseppe De Laurentis, Harald Ita, Ben Page +1
We present compact two-loop QCD corrections in the leading-color approximation for the production of an electroweak vector boson, , in association with…
Two-Loop Five-Point Two-Mass Planar Integrals and Double Lagrangian Insertions in a Wilson Loop
Samuel Abreu, Dmitry Chicherin, Vasily Sotnikov +1
We consider the complete set of planar two-loop five-point Feynman integrals with two off-shell external legs. These integrals are relevant, for instance, for the calculation of th…
Next-to-next-to-leading order event generation for Z-boson production in association with a bottom-quark pair
Javier Mazzitelli, Vasily Sotnikov, Marius Wiesemann
We consider the production of a Z boson decaying to leptons in association with a bottom-quark pair in hadronic collisions. For the first time, we compute predictions at next-to-ne…
Double-Virtual NNLO QCD Corrections for Five-Parton Scattering: The Quark Channels
Giuseppe De Laurentis, Harald Ita, Vasily Sotnikov
We complete the computation of two-loop helicity amplitudes required to obtain next-to-next-to-leading order QCD corrections for three-jet production at hadron colliders, including…
Double-Virtual NNLO QCD Corrections for Five-Parton Scattering: The Gluon Channel
Giuseppe De Laurentis, Harald Ita, Maximillian Klinkert +1
We compute the two-loop helicity amplitudes for the scattering of five gluons, including all contributions beyond the leading-color approximation. The analytic expressions are repr…
Complete contributions to four-loop pure-singlet splitting functions
Thomas Gehrmann, Andreas von Manteuffel, Vasily Sotnikov +1
The scale evolution of parton distributions is determined by universal splitting functions. As a milestone towards the computation of these functions to four-loop order in QCD, we…
All Two-Loop Feynman Integrals for Five-Point One-Mass Scattering
Samuel Abreu, Dmitry Chicherin, Harald Ita +4
We compute the complete set of two-loop master integrals for the scattering of four massless particles and a massive one. Our results are ready for phenomenological applications, r…
Leading-Color Two-Loop QCD Corrections for Three-Photon Production at Hadron Colliders
S. Abreu, B. Page, E. Pascual +1
We compute the two-loop helicity amplitudes for the production of three photons at hadron colliders in QCD at leading-color. Using the two-loop numerical unitarity method coupled w…
Caravel: A C++ Framework for the Computation of Multi-Loop Amplitudes with Numerical Unitarity
S. Abreu, J. Dormans, F. Febres Cordero +6
We present the first public version of Caravel, a C++17 framework for the computation of multi-loop scattering amplitudes in quantum field theory, based on the numerical unitarity…
