We present the analytic form of all leading-color two-loop five-parton helicity amplitudes in QCD. The results are analytically reconstructed from exact numerical evaluations over finite fields. Combining a judicious choice variables with new approach to treatment particle states $D$ dimensions for evaluation amplitudes, we obtain expressions modest computational effort. Their systematic simplification using multivariate partial-fraction decomposition leads particularly compact form. Our...
We present the analytic form of planar two-loop five-gluon scattering amplitudes in QCD for a complete set independent helicity configurations external gluons. These include first results five-point relevant computation next-to-next-to-leading-order corrections at hadron colliders. The were obtained by reconstructing expressions from numerical evaluations. complexity is reduced exploiting physical and analytical properties amplitudes, employing minimal basis so-called pentagon functions that...
We present the first public version of Caravel, a C++17 framework for computation multi-loop scattering amplitudes in quantum field theory, based on numerical unitarity method. Caravel is composed modules $D$-dimensional decomposition integrands into master and surface terms, tree-level floating point or finite-field arithmetic, one- two-loop QCD Einstein gravity, functional reconstruction tools. provide programs that showcase Caravel's main functionalities allow to compute selected amplitudes.
The Future Circular Collider (FCC) at CERN, a proposed 100-km circular facility with several colliders in succession, culminates 100 TeV proton-proton collider. It offers vast new domain of exploration particle physics, orders magnitude advances terms Precision, Sensitivity and Energy. implementation plan foresees, as first step, an Electroweak Factory electron-positron This high luminosity facility, operating between 90 365 GeV centre-of-mass energy, will study the heavy particles Standard...
The operation of the Large Hadron Collider (LHC) has been a great success with Run 1 culminating in discovery Higgs boson by ATLAS and CMS experiments 2012. In 2, LHC have moved towards performing high precision measurements uncertainties reaching below percent level for certain observables. Looking forward to Future Circular electron beams (FCC-ee), which will operate experimentally much cleaner environment electron-positron initial states, there be an even more dramatic increase...
