A multi-event interface for next-to-leading order calculations in MadGraph5_aMC@NLO

Rikkert Frederix, Stefan Roiser, Robert Schöfbeck +2

We detail the implementation of a multi-event interface for next-to-leading order (NLO) calculations in MadGraph5_aMC@NLO, allowing tree-level scattering amplitudes for multiple ph…
