Two-loop leading-color QCD corrections for Higgs plus two-jet production in the heavy-top limit
Giuseppe De Laurentis, Harald Ita, Viktor Kuschke +2
We present the leading-color two-loop QCD corrections for Higgs-boson production in association with two jets through gluon fusion in the heavy-top effective theory. We provide ana…
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…
Accelerating Berends-Giele recursion for gluons in arbitrary dimensions over finite fields
Juan M. Cruz-Martinez, Giuseppe De Laurentis, Mathieu Pellen
This work provides a proof of concept for the computation of pure gluonic amplitudes in quantum chromodynamics (QCD) on graphics processing units (GPUs). The implementation relies…
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…
Compact Two-Loop QCD Corrections for Production in Proton Collisions
Giuseppe De Laurentis, Harald Ita, Ben Page +1
We present compact two-loop QCD corrections in the leading-color approximation for the production of an electroweak vector boson, $V = \{W^{\pm}, Z,γ^\star\}$, in association with…
