Understanding SUSY limits from LEP

TL;DR

This paper reviews LEP experimental results to understand their implications for supersymmetry models, focusing on the MSSM and SUGRA scenarios, and discusses the dependence of these results on model assumptions.

Contribution

It provides a detailed analysis of LEP constraints on SUSY models within MSSM and SUGRA frameworks, highlighting model dependence and coverage.

Findings

LEP results heavily constrain the MSSM parameter space.

Hints for a light Higgs boson are discussed.

Evidence for SUSY-assisted gauge coupling unification is examined.

Abstract

LEP results have constrained heavily the Minimal Supersymmetric Standard Model, while providing hints for light Higgs boson and for ``SUSY-assisted'' gauge couling unification. In this paper the results obtained at LEP within two scenarios, the gravity-mediated MSSM framework and the minimal SUGRA scenario are presented. Model-dependence and coverage of LEP results is discussed.
