IS (Low Energy) SUSY STILL ALIVE?

TL;DR

This paper reviews the current status of low-energy supersymmetry, its theoretical foundations, experimental searches at the LHC, and the remaining viable parameter space in the Minimal Supersymmetric Standard Model.

Contribution

It provides a comprehensive overview of supersymmetry, including theoretical background, phenomenological features, experimental limits, and future prospects at colliders.

Findings

Current experimental limits constrain supersymmetric particles

Allowed parameter space of the MSSM is still viable

Potential signatures of supersymmetry at the LHC are discussed

Abstract

Supersymmetry, a new symmetry that relates bosons and fermions in particle physics, still escapes observation. Search for supersymmetry is one of the main aims of the Large Hadron Collider. The other possible manifestation of supersymmetry is the Dark Matter in the Universe. The present lectures contain a brief introduction to supersymmetry in particle physics. The main notions of supersymmetry are introduced. The supersymmetric extension of the Standard Model -- the Minimal Supersymmetric Standard Model -- is considered in more detail. Phenomenological features of the Minimal Supersymmetric Standard Model as well as possible experimental signatures of supersymmetry at the Large Hadron Collider are described. The present limits on supersymmetric particles are presented and the allowed region of parameter space of the MSSM is shown.
