Detection of long-lived staus and gravitinos at the ILC

Abstract

A study is presented illustrating the excellent potential of future International Linear Collider (ILC) experiments to detect metastable staus $\text{stau}$, measure precisely their mass and lifetime, and to determine the mass of the gravitino $\text{sG}$ from the decay $\text{stau}\to \tau \text{sG}$, thus providing direct access to the gravitational coupling, respectively Planck scale.
