"Road to Minimal WIMPs"

Minimal WIMP models extend the Standard Model with an electroweak multiplet whose neutral component χ serves as Dark Matter (DM). Direct Detection (DD) and Indirect Detection (ID)
searches probe these models especially when χ accounts for 100% of DM (the thermal target). Colliders aim to produce the charged members of the multiplet, which produce interesting signals when they decay. These searches are more effective when χ accounts for a fraction of DM, as this leads to a lower mass multiplet and larger production cross sections. This shows an interesting complementarity between DD, ID, and colliders. In this talk, I discuss the role that present and future colliders can play in discovering Minimal WIMPs. I show how a 3 TeV muon collider can discover the elusive doublet (Higgsino-like) state up to its thermal target. As the collider energy increases, larger multiplets become accessible. A 10 TeV muon collider could discover the triplet (Wino-like) state up to its thermal target as well as a quintuplet state that accounts for ~10% of DM. These results indicate an interesting path ahead towards the possible discovery of the long standing minimal WIMPs.
