Les Houches Squared Event Generator for the NMSSM

We present a generic framework for event generation in the Next-to-Minimal Supersymmetric Standard Model (NMSSM), including the full chain of production process, resonance decays, parton showering, hadronization, and hadron decays. The framework at present uses NMHDECAY to compute the NMSSM spectrum and resonance widths, CALCHEP for the generation of hard scattering processes, and PYTHIA for resonance decays and fragmentation. The interface between the codes is organized by means of two Les Houches Accords, one for supersymmetric mass and coupling spectra (SLHA,2003) and the other for the event generator interface (2000).
