Plasma panel detectors are a variant of micropattern detectors that are sensitive to ionizing radiation. They are motivated by the design and operation of plasma display panels. The detectors consist of arrays of electrically and optically isolated pixels defined by metallized cavities embedded in a dielectric substrate. These are hermetically sealed gaseous detectors that use exclusively...

Many extensions of the Standard Model (SM) include particles that are neutral, weakly coupled, and long-lived that can decay to final states containing several hadronic jets. Long-lived particles (LLPs) can be detected as displaced decays from the interaction point, or missing energy if they escape. ATLAS and CMS have performed searches at the LHC and significant limits have been set in recent...
