A Mini Review of some Dark Matter/BSM Physics and a Bit More

Abstract

There is a vast literature on Dark Matter (DM) with many reviews of specific topics only a small fraction of which will be mentioned. I start with a very brief review of cosmology which underlies much of DM research and some relevant General Relativity (GR). I next discuss Self Interacting Dark Matter (SIDM) models and upper bounds on the mass M(X) of point-like, symmetric DM. This is followed up by some general aspects of DM detection and directional and temporal variations. I discuss DM models tied with BSM physics scenarios including Primordial Black Holes, new physics in the neutrino sector, ultra-light DM and axions.
