Polarization structure and spin covariance of massive vector-boson amplitudes in QCD
Giuseppe De Laurentis, Kirill Melnikov, Matteo Tresoldi
Nearly thirty years ago, Bern, Dixon and Kosower computed all helicity amplitudes for the annihilation of an electron-positron pair into four QCD partons through an electroweak vec…
An analytic result for the amplitude
John M. Campbell, Giuseppe De Laurentis, R. Keith Ellis
We present a fully analytic calculation of the leading-order one-loop amplitude for triple Higgs production via gluon fusion, , retaining full dependence on the mass of…
Analytic reconstruction with massive particles: one-loop amplitudes for
John M. Campbell, Giuseppe De Laurentis, R. Keith Ellis
We present an analytic reconstruction of one-loop amplitudes for the process . Our calculation is a novel use of analytic reconstruction, retaining explici…
The Two-Loop Lipatov Vertex in QCD
Samuel Abreu, Giuseppe De Laurentis, Giulio Falcioni +3
High-energy factorization of 2 -> 2 amplitudes in QCD has been recently pushed to the next-to-next-to-leading logarithmic order by determining the three-loop gluon Regge trajectory…
