Description
The ATLAS detector is sensitive to the decay of neutral, weakly
interacting, long-lived particles. Such decays can leave unique,
detectable, signatures. This poster concentrates on preliminary results
from a search for decays in the hadronic calorimeter in Run II: the search
strategy looks for hadronic-only-calorimeter jets that have little or no
tracks pointing at them. Many models can contain final states like this:
Stealth SUSY, Baryogenesis, and a simple hidden sector scalar that decays
to heavy fermion jets. Performance of the ATLAS Calorimeter Ratio trigger
along with tools and preliminary results are shown.
