Complex dark sectors with long-lived states could maybe mean that the DM in the earlier stages of the universe could have had different properties than the DM today. What possibilities and constraints do we have for this? What consequences would such possibilities have on our conclusions and constraints? If you know of any good papers that could help to set up a proper discussions on this at the next meeting, feel free to post them in Slack or bring them up here!
