The Four-Jet Rate in Electron-Positron Annihilation at Order
Xuan Chen, Dmitry Chicherin, Elliot Fox +6
We compute for the first time the production rate for four jets in electron-positron annihilation at next-to-next-to-leading order. Our calculation exhibits the highest final-state…

Jet production at electron-positron colliders at next-to-next-to-next-to-leading order in QCD
Xuan Chen, Petr JakubÄÃk, Matteo Marcoli +1
We present the first application of antenna subtraction at next-to-next-to-next-to-leading order (NLO) in QCD by computing fully differential predictions for two-jet production…

Phase-space sectors for ordered momentum mappings in local subtraction up to NLO
Xuan Chen, Matteo Marcoli
Ordered momentum mappings present optimal convergence in soft and collinear configurations and are particularly suitable for the numerical implementation of local subtraction schem…
