Event details
Multiloop and multileg scattering amplitudes are key ingredients for achieving higher theoretical precision ahead of the high-luminosity run of the LHC. In this talk, I will present recent results on three-loop Feynman integrals and amplitudes for vector boson + jet and Higgs + jet production in the heavy-top-mass limit at hadron colliders. I will also discuss the computational advances underlying these calculations, including the derivation of a minimal tensor basis, the identification of canonical master integrals, and the construction of a graded basis of transcendental functions tailored to specific scattering processes.
About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
