Interpolating amplitudes
VÃctor Bresó, Gudrun Heinrich, Vitaly Magerya +1
The calculation of scattering amplitudes at higher orders in perturbation theory has reached a high degree of maturity. However, their usage to produce physical predictions within…
One-Loop Calculations in Effective Field Theories with GoSam-3.0
Jens Braun, Benjamin Campillo Aveleira, Gudrun Heinrich +5
We present a major update of the one-loop generator GoSam, containing performance improvements as well as new features, in particular functionalities that facilitate calculations b…
Master integrals for semi-inclusive cuts of massless four-loop propagators
Vitaly Magerya, Levente Fekésházy
We present the analytic calculation of all master integrals for 3-, 4-, and 5-particle semi-inclusive cuts of four-loop massless propagators by means of differential equations. We…
Event Generators for High-Energy Physics Experiments
J. M. Campbell, M. Diefenthaler, T. J. Hobbs +221
We provide an overview of the status of Monte-Carlo event generators for high-energy particle physics. Guided by the experimental needs and requirements, we highlight areas of acti…
