Adding a sector containing dark photons to the Lagrangian of the Standard Model can be done in a straightforward and minimal way by introducing a new U(1) gauge field. The specifics of the interaction between this new field, potential new particle content (e.g., a Dirac fermion for dark matter) and the Standard … See more The dark photon (also hidden, heavy, para-, or secluded photon) is a hypothetical hidden sector particle, proposed as a force carrier similar to the photon of electromagnetism but potentially connected to See more Direct conversion A massive dark photon candidate with kinetic mixing strength $${\displaystyle \epsilon }$$ could spontaneously convert to a Standard Model See more Observations of gravitational effects that cannot be explained by visible matter alone imply the existence of matter which does not or does only very weakly couple to the known forces of nature.

WebMar 23, 2024 · A coupling of a dark photon A′ from a U(1)A′ with the standard model (SM) particles can be generated through kinetic mixing represented by a parameter ϵ. A non-zero ϵ also induces a mixing between A′ and Z if dark photon mass mA′ is not zero. This mixing can be large when mA′ is close to mZ even if the parameter ϵ is small. Many efforts have …
