Simulated decay into standard model particles with MadGraph 5

Analyzed scenarios with and without stable neutral remnants

Abstract

We begin the investigation of the decay of quantum black holes with masses of the order of the TeV, possibly produced at the Large Hadron Collider, within the framework of MadGraph 5, a standard particle physics Monte Carlo event generator. We write an effective Lagrangian to describe the black hole decay and examine both the possibility of a complete decay into standard model particles with or without the associated production of a very massive stable neutral remnant.
