Philippe Mermod (for the ATLAS Collaboration)
TL;DR
This paper evaluates ATLAS's ability to discover R-hadrons predicted by supersymmetry, focusing on gluino and stop-based particles, using specific observables and demonstrating potential detection at relatively low luminosity for masses up to 1 TeV.
Contribution
It presents the first detailed study of ATLAS's discovery potential for R-hadrons in various supersymmetric scenarios using multiple observables.
Findings
ATLAS can discover R-hadrons up to 1 TeV with 1fb-1 luminosity.
High transverse momentum muon-like signals are effective indicators.
Ionization energy loss measurements enhance detection sensitivity.
Abstract
R-hadrons are predicted in a range of supersymmetric scenarios including split-supersymmetry and gauge-mediated supersymmetry breaking. In this paper, the discovery potential of the ATLAS experiment for gluino and stop-based R-hadrons is outlined. A range of final state observables such as high transverse momentum muon-like objects and information on ionization energy loss is used. It is shown that ATLAS would be able to discover such particles at comparatively modest amounts of luminosity (1fb-1) for masses up to 1 TeV.
