Résumé |
In cosmological scenarios beyond thermal freeze-out dark matter interactions with standard-model
particles can be tiny. This leads to mediators with a lifetime that is long compared with the scales of
particle colliders. In this talk I will discuss two new ideas for collider searches with long-lived mediators:
soft displaced objects as signs of compressed dark sectors at the LHC; and displaced vertices from long-
lived light scalars at Belle II. I will show that novel search strategies allow us to explore dark matter
interactions ranging over several orders of magnitude. |
