The classical two-loop amplitude at leading logarithmic accuracy for graviton emission in multi-Regge kinematics
Federico Buccioni, Vittorio Del Duca, Emanuele Rosi
Using the gravitational shockwave formalism, we compute the classical part of the five-point amplitude at leading logarithmic accuracy describing the emissio…

Interference effects in gluon-fusion Higgs boson production
Federico Buccioni, Federica Devoto
In this contribution we summarize recent progress in higher-order computations of signal-background interference effects in Higgs boson production via gluon fusion. The focus is on…

Two-Loop Spacelike Splitting Amplitudes in Full-Color QCD
Federico Buccioni, Hanyu Fang, Kai Yan
The study of QCD scattering amplitudes in the collinear regime provides crucial insight into the factorization properties of hadronic cross sections. In this paper, we present the…
