It's On: Early Interpretations of ATLAS Results in Jets and Missing Energy Searches

TL;DR

This paper reports early ATLAS search results for supersymmetry, setting new limits on gluino masses in jets and missing energy signatures, surpassing previous collider constraints.

Contribution

It provides initial interpretations of ATLAS data in jets and missing energy channels, extending the exclusion limits for gluino masses beyond Tevatron results.

Findings

Gluino masses below 205 GeV are excluded regardless of LSP mass.

Coverage extends up to approximately 295 GeV for certain spectra.

First ATLAS results significantly improve previous collider constraints.

Abstract

The first search for supersymmetry from ATLAS with 70/nb of integrated luminosity extends the Tevatron' s reach for colored particles that decay into jets plus missing transverse energy. For gluinos that decay directly or through a one step cascade into the LSP and two jets, the mass range m_g < 205 GeV is disfavored by the ATLAS searches, regardless of the mass of the LSP. In some cases the coverage extends up to m_g ~ 295 GeV, already surpassing the Tevatron's reach for compressed supersymmetry spectra.
