Hello! I read several papers about different model of DM beyond basic WIMPs and axions but haven't found a lot about DM effects on baryon asymmetry. I was wondering, is it possible to have a type of DM that decays (or at least it did a lot in the past) preferably more to matter than antimatter? Or is there some fundamental symmetry that prevents this? Also if you know some papers that talk about this, I would really appreciate if you can point me towards them. Thank you!
