Reference Physics Lists LHEP –fastest of all physics lists –not the most precise –contains standard EM processes –good at describing showers in detectors QGSP_BERT –the physics list most recommended for HEP –used by ATLAS –contains standard EM processes –uses Bertini cascade for hadrons of energy below ~10 GeV –uses QGS model for high energies (> 20 GeV) 5
