Dissecting Jets and Missing Energy Searches Using $n$-body Extended Simplified Models

Understand

Simplified Models are a useful way to characterize new physics scenarios for the LHC.

• Particle decays are often represented using non-renormalizable operators that involve the minimal number of fields required by symmetries.
• Generalizing to a wider class of decay operators allows one to model a variety of final states.
• This approach, which we dub the $n$-body extension of Simplified Models, provides a unifying treatment of the signal phase space resulting from a variety of signals.
