First look at the evaluation of two-loop Feynman integrals for radiative return processes
Mattia Pozzoli, William J. Torres Bobadilla
Precision studies of radiative return processes at low-energy electron--positron colliders require next-to-next-to-leading order QED predictions retaining full dependence on the el…
Electroweak corrections to Higgs boson pair production: The quark channel
Marco Bonetti, Gudrun Heinrich, Philipp Rendler +1
We present the mixed QCD-electroweak corrections to Higgs boson pair production in the quark-antiquark channel. The virtual amplitudes are computed fully analytically using the met…
Tensor decomposition of to higher orders in the dimensional regulator
Thomas Dave, Jérémy Paltrinieri, Pau Petit Rosàs +1
We present a first study of the scattering process beyond next-to-leading order, aimed at providing preliminary insights required for future NNLO predictions…
Radiative return meets GVMD
Pau Petit Rosà s, Olga Shekhovtsova, William J. Torres Bobadilla
We improve the description of pion-photon interactions in the radiative return process at the next-to-leading order by including the pion form factor in the…
Three-loop helicity amplitudes of four-lepton scattering in QED
Giulio Crisanti, Thomas Dave, Pierpaolo Mastrolia +3
We present the analytic expressions of the three-loop virtual corrections to the helicity amplitudes of 2 -> 2 four-fermion scattering processes in massless QED. The contributing F…
Six-loop gravitational interactions at the sixth post-Newtonian order
Giacomo Brunello, Manoj K. Mandal, Pierpaolo Mastrolia +6
We compute the gravitational interaction of two coalescing compact objects at sixth post-Newtonian order in the static limit, employing the diagrammatic approach within the effecti…
