Status of Dark Photons
arXiv:2405.08534
Abstract
I review recent developments in the field of dark photons-here taken to be U(1) gauge bosons with mass less than the Z-including both kinetically mixed vectors and those that couple to anomaly-free U(1)'s. Distinctions between Higgs and Stueckelberg masses are highlighted, with discussion of swampland constraints, UV completions, and new experimental search strategies.
