Hadronic shower simulation for the H1 detector; Hdaronische Schauersimulation fuer den H1-Detektor

Abstract

A precise and fast simulation of electromagnetic and hadronic showers is required to determine the influence of the properties of the H1 detector on the results of physics analysis. A new method (H1FAST) to simulate electromagnetic and hadronic showers in complex detectors is introduced. The most important elements are the simulation of parametrized electromagnetic subshowers within the GEANT framework, the explicit generation of secondary particles from hadronic interactions, the space and energy dependent termination of nucleons and photons, and the analytic computation of the sampling effects using simple parametrizations. Experimental data of calorimeter tests done at CERN for pions in the energy range 5 - 205 GeV are compared with H1FAST simulations. The inelastic hadron nucleon scattering is simulated by the GHEISHA- or a special H1FLUKA-generator. It is shown that the H1FAST algorithm is able to reproduce the experimental results with a very high precision. The comparison of h/e-ratios gives maximum deviations with respect to the experiment of less than 1% (2.5%) for the H1FLUKA (GHEISHA) generator. Detailed simulations of hadronic jets are used to verify the H1FAST algorithm for the H1 detector. The required CPU time is 15-25 s/event (DESY-IBM 3090) for the simulation of neutral current events with  More>>

[Deutsch] Eine genaue und schnelle Simulation elektromagnetischer und hadronischer Schauer ist erforderlich, um den Einfluss der Detektoreigenschaften auf die Ergebnisse einer Analyse sehr genau bestimmen zu koennen. Es wird ein neues, als H1FAST bezeichnetes Verfahren zur Simulation elektromagnetischer und hadronischer Schauer in komplexen Detektoren vorgestellt. Wichtigste Elemente sind die Simulation parametrisierter elektromagnetischer Subschauer im GEANT-System, die explizite Erzeugung hadronischer Endzustaende, die orts- und energieabhaengige Terminierung von Nukleonen und Photonen sowie die analytische Berechnung der Sampling-Effekte mit Hilfe einfacher Parametrisierungen. Experimentelle Daten des CERN-Kalorimetertests fuer Pionen mit Energien von 5-205 GeV werden mit H1FAST-Simulationen verglichen. Dabei wird die Simulation der Hadron-Kern-Wechselwirkungen mit dem GHEISA- bzw. einem speziellen H1FLUKA-Modell durchgefuehrt. Es wird gezeigt, dass der H1FAST-Algorithmus die experimentellen Ergebnisse mit grosser Genauigkeit reproduzieren kann. Der Vergleich der h/e-Verhaeltnisse ergibt maximale Abweichungen gegenueber dem Experiment von weniger als 1% (2.5%) mit dem H1FLUKA- (GHEISA-) Generator. Detaillierte Simulationen hadronischer Jets werden verwendet, um das vorgestellte Verfahren fuer den H1-Detektor zu verifizieren. Der Rechenzeitbedarf betraegt 15-25 s/Ereignis (DESY-IBM 3090) fuer die Simulation neutraler Stromereignisse mit Impulsuebertraegen von 50-5000 GeV{sup 2}. (orig.).}
