Dark photon theory
WebSep 26, 2024 · Centre Authors: Tobar, M., McAllister, B. WebMay 4, 2024 · The dark photon is a new gauge boson whose existence has been conjectured. It is dark because it arises from a symmetry of a hypothetical dark sector comprising particles completely neutral under the Standard Model interactions. Dark though it is, this new gauge boson can be detected because of its kinetic mixing with the …
