“Next-to-leading order predictions matched to parton showers for new physics”

 

 

 

"During the first LHC run, both the ATLAS and CMS collaborations have extensively investigated many different channels in order to get hints for new physics. Many of these searches are currently based on Monte Carlo simulations of the signals where leading-order matrix elements of different partonic multiplicities are matched to parton showers and merged. More sophisticated differential theoretical predictions are however always helpful for setting more accurate exclusion limits, possibly refining the search strategies, and measuring the model free parameters in case of a discovery. In this talk, I will discuss how the MadGraph5_aMC@NLO framework can provide a general platform for computing (differential) observables within many beyond the Standard Model theories at the next-to-leading order accuracy in QCD. I will present specific examples based on scenarios inspired by supersymmetry and on vector-like quark models."
