Charged Higgs Boson Detector Aspects

The discovery potential for charged Higgs bosons has been studied including background simulations for sqrts = 500 GeV and a luminosity of 10 fb-1 depending on the hadronic calorimeter resolution of a LC500 detector. The hadronic decay channel H+H- --> cscs is in particular suited for this study due to a large sensitivity dependence on the hadron calorimeter performance. For this study a hadronic energy resolution as achieved at LEP experiments is sufficient to reach a very good sensitivity. A calorimeter with weaker energy resolution would reduce the sensitivity by a factor of two.
