Uncertainties in track momentum due to multiple scattering in a forward spectrometer

Abstract

The influence of multiple scattering on the momentum resolution for a forward spectrometer is investigated. Two cases, with and without track measurements inside the magnet, are discussed. A simple relation between angular and momentum resolutions and multiple scattering inside the magnet is derived and confirmed with Monte Carlo generated events subjected to a detailed simulation and full reconstruction for a real spectrometer.
