Simulation of Beyond Standard Model Physics in Herwig++

Abstract

We present a new approach for the simulation of Beyond Standard Model (BSM) physics within the Herwig++ event generator. Our approach is more generic than previous methods with the aim of minimising the effort of implementing further new physics models. Spin correlations, which are important for BSM models due to new heavy fermions and bosons, are discussed and their effects demonstrated for the Minimal Supersymmetric Standard Model (MSSM) and Randall-Sundrum Model using our new framework.
