Automated event generation for loop-induced processes

We present the first fully automated implementation of cross-section computation and event generation for loop-induced processes. This work is integrated in the MADGRAPH5_AMC@NLO framework. We describe the optimisations implemented at the level of the matrix element evaluation, phase space integration and event generation allowing for the simulation of large multiplicity loop-induced processes. Along with some selected differential observables, we illustrate our results with a table showing inclusive cross-sections for all loop-induced hadronic scattering processes with up to three final states in the SM as well as for some relevant 2 -> 4 processes. Many of these are computed here for the first time.
