Leading-Color Two-Loop Amplitudes for Four Partons and a W Boson in QCD
/ Abreu, S. (CERN ; U. Edinburgh, Higgs Ctr. Theor. Phys. ; UCLA, Los Angeles (main)) ; Febres Cordero, F. (Florida State U.) ; Ita, H. (Freiburg U.) ; Klinkert, M. (Freiburg U.) ; Page, B. (CERN) ; Sotnikov, V. (Munich, Max Planck Inst.)
We present the leading-color two-loop QCD corrections for the scattering of four partons and a $W$ boson, including its leptonic decay. The amplitudes are assembled from the planar two-loop helicity amplitudes for four partons and a vector boson decaying to a lepton pair, which are also used to determine the planar two-loop amplitudes for four partons and a $Z/\gamma^*$ boson with a leptonic decay. [...]

Caravel: A C++ framework for the computation of multi-loop amplitudes with numerical unitarity
/ Abreu, S (Louvain U., CP3) ; Dormans, J (Freiburg U.) ; Febres Cordero, F (Florida State U.) ; Ita, H (Freiburg U.) ; Kraus, M (Florida State U.) ; Page, B (IPhT, Saclay) ; Pascual, E (Freiburg U.) ; Ruf, M S (Freiburg U., Inst. Phys. Chem.) ; Sotnikov, V (Munich, Max Planck Inst.)
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 method. Caravel is composed of modules for the $D$-dimensional decomposition of integrands of scattering amplitudes into master and surface terms, the computation of tree-level amplitudes in floating point or finite-field arithmetic, the numerical computation of one- and two-loop amplitudes in QCD and Einstein gravity, and functional reconstruction tools.

Computing Planar Five-Gluon Amplitudes with Numerical Unitarity
/ Abreu, Samuel (Freiburg U.) ; Febres Cordero, Fernando (Freiburg U.) ; Ita, Harald (Freiburg U.) ; Page, Ben (Freiburg U.) ; Zeng, Mao (UCLA)
We discuss the numerical unitarity method for the computation of two-loop scattering amplitudes relevant for LHC phenomenology. We extend one-loop technologies by making use of novel ideas such as a geometric construction of surface terms and finite field numerics. [...]

This report summarises the properties of Standard Model processes at the 100 TeV pp collider. We document the production rates and typical distributions for a number of benchmark Standard Model processes, and discuss new dynamical phenomena arising at the highest energies available at this collider.
