Particle and Astroparticle Searches for Supersymmetry

TL;DR

This paper comprehensively analyzes collider, precision, and dark matter searches for supersymmetry within minimal supergravity, highlighting their complementarity and implications for future experiments.

Contribution

It extends previous analyses by including the focus point region and all promising indirect dark matter searches, providing a more complete coverage of parameter space.

Findings

Particle and astrophysical searches are highly complementary.

Combined searches probe nearly all models in parameter space.

Cosmology alone does not set useful upper bounds on superpartner masses.

Abstract

Supersymmetry may be discovered at high energy colliders, through low energy precision measurements, and by dark matter searches. We present a comprehensive analysis of all available probes in minimal supergravity. This work extends previous analyses by including the focus point branch of parameter space and the full array of promising indirect dark matter searches. We find that particle and astrophysical searches underway are highly complementary: each separately provides only partial coverage of the available parameter space, but together they probe almost all models. Cosmology does {\em not} provide upper bounds on superpartner masses useful for future colliders. At the same time, in the cosmologically preferred region, if supersymmetry is to be observable at a 500 GeV linear collider, some signature of supersymmetry must appear {\em before} the LHC.
