Abstract

By using the tungsten as passive element and the Glass Resistive Plate Chambers (GRPCs) as active element, the gaseous hadronic calorimeter is studied as a possible detector for the future International Linear Collider (ILC). The results of the numerical study, using the GEANT4 simulation package, of the performance of this calorimeter when it is exposed to a negative pion beam in an energy range from 5 GeV to 100 GeV are presented in this paper. Operating characteristics of this prototype, such as signal linearity, energy resolution and reconstructed energy have been simulated and examined. Moreover, a comparison between the Digital Hadron Calorimeter (DHCAL) and the Analog Hadron Calorimeter (AHCAL) is made.   Key words: Calorimetry, resistive plate chambers, international linear collider (ILC), GEANT4.

Summary

Introduction

Among the most important objectives of future particle physics experiments at the international linear collider (ILC) [ILC reference design report (RDR); ILC Homepage http://www.linearcollider.org/cms/.] are searching for one or more Higgs particles and the study of their characteristics. Many interesting physics processes will be provided by the electron-positron collisions at the center-of-mass energies between 500 GeV and 1 TeV in ILC such as W, Z and H heavy bosons processes. These processes will be characterized by multi-jet. The most efficient method to achieve this resolution is particle flow algorithm (PFA). This method allows to separate, respectively the deposited energies from photons and due to hadrons and the energies deposited from the charged hadrons and due to neutral hadrons in a jet. The study of a calorimeter performance is an essential step
