3) Relic density: from coannihilation, GB says that mchi1=890 and mchi0=800 with yd=1 gives the right relic. Ongoing work (Jan, André, Genevieve) on checking the CDFO. | 3) Relic density: from coannihilation, GB says that mchi1=890 and mchi0=800 with yd=1 gives the right relic.

- | ii) Bounds on chi1 come from mono/multi-jet + MET. Some of these were recasted in Fig.7 of [[https://arxiv.org/pdf/1703.00452.pdf|this fantastic paper]] (take the XF3 shade), which means that 500-600 GeV were excluded with the ATLAS 13.3 fb-1 search, and that HL-LHC will push the bounds to 1.1 - 1.3 TeV. Bound is almost independent on the compression (mchi1-mchi0). | + | ii) Bounds on chi1 come from mono/multi-jet + MET.

iii) bounds from l + LQ, where LQ -> a) tau charm, b) top +tau and c) b nu. Easier to have the charm in the initial state, due to PDF suppression (but b is also possible). Giacomo, José and Jordan will look into existing searches that could give constraints. | iii) bounds from l + LQ, where LQ -> a) tau charm, b) top +tau and c) b nu.
