Distinguishing SUSY scenarios using \tau polarisation and \tilde\chi^0_1 Dark Matter

TL;DR

This paper proposes a method to measure tau polarization at the ILC and demonstrates how tau polarization analysis can differentiate between SUSY scenarios like mSUGRA and SUSY-GUT, aiding Dark Matter studies.

Contribution

It introduces a tau polarization measurement technique at the ILC and applies it to distinguish between different SUSY models relevant for Dark Matter.

Findings

Tau polarization measurement is feasible at the ILC using 1-prong hadronic decays.

Tau polarization analysis effectively differentiates mSUGRA and SUSY-GUT scenarios.

The method enhances understanding of SUSY models' implications for Dark Matter.

Abstract

We discuss first a method of measuring $\tau$ polarisation at the ILC using the 1--prong hadronic decays of the $\tau$. We then show in this contribution how a study of the $\tilde \tau$ sector and particularly use of decay $\tau$ polarisation can offer a very good handle for distinguishing between mSUGRA and a SUSY-GUT scenario, both of which can give rise to appropriate Dark Matter.
