Testing the Anomaly Mediation at the LHC

TL;DR

This paper explores how to test anomaly-mediated supersymmetry breaking models at the LHC, focusing on gaugino properties when scalars are too heavy to detect, and proposes strategies for experimental verification.

Contribution

It introduces a method to analyze gaugino signatures at the LHC within anomaly-mediation models with heavy scalars, providing a new approach for testing supersymmetry.

Findings

Gauginos are the only accessible superparticles at the LHC in this model.

Strategies for distinguishing anomaly-mediation signatures from other models.

Insights into the mass spectrum and decay patterns of gauginos.

Abstract

We consider a supersymmetric model in which gaugino masses are generated by the anomaly-mediation mechanism while scalar masses are from tree-level supergravity interaction. In such a model, scalar fermions as well as Higgsinos become as heavy as O(10-100TeV) and hence only the gauginos are superparticles kinematically accessible to the LHC. We study how and how well the properties of gauginos can be studied. We also discuss the strategy to test the anomaly-mediation model at the LHC.
