Multi-channel phase space with Feynman-diagram-gauge amplitudes
Kaoru Hagiwara, Junichi Kanzaki, Fabio Maltoni +2
Multi-channel phase space with a single Feynman diagram enhancement is a powerful tool for high-energy physics event generation if a diagram with a singular propagator dominates th…
Prospects for toponium formation at the LHC in the single-lepton mode
Benjamin Fuks, Kaoru Hagiwara, Kai Ma +2
We investigate the formation of toponium in the single-leptonic final state at the LHC. Our study builds on our recently proposed framework that incorporates the associated non-per…
Simulating toponium formation signals at the LHC
Benjamin Fuks, Kaoru Hagiwara, Kai Ma +1
We present a method to simulate toponium formation events at the LHC using the Green's function of non-relativistic QCD in the Coulomb gauge, which governs the momentum distributio…
One-loop QCD amplitudes in the Feynman-Diagram gauge
Kaoru Hagiwara, Kentarou Mawatari, Youichi Yamada +1
Scattering amplitudes for the massless QCD process, , are calculated in the one-loop order in the Feynman-Diagram (FD) gauge, where gluons are q…
W-boson pair production at lepton colliders in the Feynman-diagram gauge
Hiroyuki Furusato, Kentarou Mawatari, Yutaro Suzuki +1
We calculate helicity amplitudes for analytically in the Feynman-diagram (FD) gauge. We show that, unlike in the unitary gauge, there is no energy growth of the…
Automatic generation of helicity amplitudes in Feynman-Diagram gauge
Kaoru Hagiwara, Junichi Kanzaki, Olivier Mattelaer +2
We develop a method to calculate helicity amplitudes of an arbitrary tree-level process in Feynman-Diagram (FD) gauge for an arbitrary gauge model with MadGraph5_aMC@NLO. We start…
