 **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).

 +(from Jan: "MG gives me an error on hypercharge violation, should be checked"​).
 +(from Benj: "The error is because mass and gague eigenstates are involved, and no hypercharge can be defined. Just ignore it").
  
 4) Investigate how to improve S/B (e.g. Br(B->l v)=10%, a third lepton veto, B is displaced in signal but not in background etc). 4) Investigate how to improve S/B (e.g. Br(B->l v)=10%, a third lepton veto, B is displaced in signal but not in background etc).
