Since the first detections of gravitational waves from merging binary black holes, there has been a renewed interest in the possibility that at least some of these black holes could be primordial in origin and that these primordial black holes (PBHs) could make up a substantial fraction of the dark matter (DM). I will briefly summarize the changing landscape of constraints on PBHs as a DM...
When revisiting studies of effective interactions between fermionic dark matter and photons, we noticed that previous treatments violate gauge invariance, which, as is usual, has huge consequences. In arXiv:2005.12789 we address this and present an update on the collider, direct and indirect experimental constraints for operators of dimension 5 and 6. Unlike previous works, we stress the...
