**Goal** : study if it's possible to tag SM hadrons (b's going to B's which in turn decay to J/psi's etc) in dark matter long-lived particle searches, when the mass splitting between the parent particle and dark matter is relatively small (< 35 GeV or so). | **Goal** : study if it's possible to tag SM hadrons (b's going to B's which in turn decay to J/psi's etc) in dark matter long-lived particle searches, when the mass splitting between the parent particle and dark matter is relatively small (< 35 GeV or so). | ||

2) Decide on a concrete model and delineate the cosmologically interesting parameter space (from conversion-driven freeze-out, freeze-in etc). Candidate model exists, with a sbottom-like parent decaying into a neutralino-like dark matter + a bottom quark. | 2) Decide on a concrete model and delineate the cosmologically interesting parameter space (from conversion-driven freeze-out, freeze-in etc).
