3 Constantly changing constraints on Primordial Black Hole dark matter

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 candidate, including bounds from evaporation, lensing, gravitational waves, accretion and dynamical effects. Previously claimed constraints on asteroid-mass PBHs have disappeared in recent years, leaving the range 10^-16 to 10^-11 solar masses as the last best hope for PBH dark matter.

5 New insights into dark matter from EFT basics

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 important effect gauge invariance has on dark matter even when its mass is well below the electroweak scale. This leads to a better picture of what we can reasonably expect from future dark matter searches. One particular insight is that anapole dark matter is unlikely to be seen soon in direct detection experiments because gauge invariance suggests that the constraints coming from the invisible width of the Z-boson are much stronger.
