Comparison of SUSY mass spectrum calculations

TL;DR

This paper compares four different computational tools for calculating the supersymmetric (SUSY) mass spectrum within the mSUGRA framework, highlighting discrepancies especially in high tan(beta) and focus point regions.

Contribution

It provides a detailed comparison of SUSY spectrum calculations from four different programs, identifying regions with significant differences.

Findings

Differences are largest in high tan(beta) regions.

Significant discrepancies occur in focus point regions.

Highlights the need for careful choice of tools in SUSY studies.

Abstract

We provide a comparison of the results of four SUSY mass spectrum calculations in mSUGRA: Isajet, SuSpect, SoftSusy, and SPheno. In particular, we focus on the high tan(beta) and focus point regions, where the differences in the results are known to be large.
