WebThis concept is formalized in the quantum theory of radiation, which has had unfailing success in explaining the interaction of electromagnetic radiation with matter, seemingly limited only by the ability of physicists to perform the indicated calculations. 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. This dark matter dominates the matter density of the universe, but its … See more • Dark radiation – Postulated type of radiation that mediates interactions of dark matter • Fifth force – Speculative fifth fundamental force See more

WebIf mirror matter does exist in large abundances in the universe and if it interacts with ordinary matter via photon-mirror photon mixing, then this could be detected in dark matter direct detection experiments such as DAMA/NaI and its successor DAMA/LIBRA. WebNov 11, 2024 · We consider a model of sub-GeV dark matter whose interaction with the Standard Model is mediated by a new vector boson (the dark photon) which couples kinetically to the photon. We describe the possibility of constraining such a model using a superfluid He-4 detector, by means of an effective theory for the description of the … s. 3999
