Automated next-to-leading order predictions for new physics at the LHC: the case of colored scalar pair production

摘要

We present for the first time the full automation of collider predictionsmatched with parton showers at the next-to-leading accuracy in QCD withinnon-trivial extensions of the Standard Model. The sole inputs required from theuser are the model Lagrangian and the process of interest. As an application ofthe above, we explore scenarios beyond the Standard Model where new coloredscalar particles can be pair produced in hadron collisions. Using simplifiedmodels to describe the new field interactions with the Standard Model, wepresent precision predictions for the LHC within the MadGraph5 aMC@NLOframework.
