Study of Sleptons at a Linear Collider - Supersymmetry Scenario SPS 1a

Abstract

The properties of the light charged sleptons in $\text{ser}\text{ser}$, $\text{smur}\text{smur}$ and ${\text{stau}}_1{\text{stau}}_1$ production are studied within the mSUGRA scenario SPS 1a. Various method are presented to determine very precisely masses, angular distributions, spin and couplings as well as the ${\text{stau}}_1$ polarisation and mixing parameter in the $\text{stau}$ sector. The analysis is based on a complete simulation of signal and background reactions assuming experimental conditions of the TESLA $e^{+}{e}^{-}$ Linear Collider.
