An overlay of all (maybe only most, this image is not kept up to date!) ATLAS and CMS LLP searches.
Charged, long-lived particle decaying into a neutral particle and a light, undetectable meson.
A shower of one or more flavours of long-lived particle, gradually decaying to detectable SM particles ("emerging").
Leptonic ID decays
A selection of signatures with LLPs leptonically decaying early enough such that
inner detector tracks can be reconstructed.
Leptonic decays outside the ID
A selection of signatures with long-lived particles leptonically decaying outside of the inner tracking detectors.
Post-calorimeter hadronic decay
A long-lived particle that decays near the end of the hadronic calorimeters but
before the middle of the muon spectrometer, leaving a shower of tracks in the muon spectrometer.
Collimated hadronic ID decay
A long-lived particle hadronically decaying in the inner detector, narrowly enough to leave only a single
reconstructable jet in the calorimeters.
Non-collimated hadronic ID decay
A long-lived particle hadronically decaying in the inner detector, where the decay products are angularly
well-separated enough to leave two reconstructable jets in the calorimeters.
Post-EM calorimeter hadronic decay
A long-lived particle hadronically decaying in or after the electromagnetic calorimeters,
leaving a jet with a very non-characteristic electromagnetic fraction.
A slightly-displaced decay of a B-meson to a K* meson and two muons, where the K*
subsequently decays to two charged pions that leave a small deposit of energy in the calorimeters.
Formation of jets (hadronization)
A sketch of how two jets might form from the production of a quark and an anti-quark.
