Precise theoretical predictions are necessary for revealing the nature of elementary particle interactions at the highest energies available at the LHC and the future collider FCC. I will review the scattering amplitudes computation starting with the leading-order (LO) and the next-to-leading-order (NLO) approximations. The recent progress at the two-loop frontier will be discussed along with next-to-next-to-leading-order (NNLO) results for \(2\rightarrow 3\) processes.

摘要

Precise theoretical predictions are necessary for revealing the nature of elementary particle interactions at the highest energies available at the LHC and the future collider FCC. I will review the scattering amplitudes computation starting with the leading-order (LO) and the next-to-leading-order (NLO) approximations. The recent progress at the two-loop frontier will be discussed along with next-to-next-to-leading-order (NNLO) results for \(2\rightarrow 3\) processes.
