Abstract

A feasibility study is presented to precisely measure the masses of charged sleptons and the lightest neutralino in e⁺e^-→\smur\smur and e⁺e^-→\stau₁\stau₁ production. Different mSUGRA scenarios with small slepton-neutralino mass differences of a few GeV are invesigated. The analysis is based on a detailed simulation of the final state lepton energy spectra including background reactions and assuming realistic experimental conditions at the TESLA e⁺e^- Linear Collider. Effects on the mass resolutions due to beams colliding head-on or under a crossing angle are discussed.
