摘要
Comparisons of higher-order predictions within the Standard Model of Particle Physics (SM) to data are central to high-energy collider experiments like the Large Hardon Collider (LHC). Processes with multiple kinematic scales, such as multi-jet and prompt photon production, provide a unique possibility for probing Quantum Chromo dynamics (QCD). These processes directly test perturbative QCD and can be used to extract fundamental parameters like the strong coupling constant and to search for BSM physics. Recent developments enabled lifting three-jet, photon + two-jet, photon-pair + jet, and three-photon cross sections to QCD's next-to-nextto-leading order (NNLO). This contribution presents phenomenological results at NNLO QCD for the three-jet and photon plus two-jet production.
