Question

what are dark photon particles?​

Answer 1

Answer:

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 dark matter.[1] In a minimal scenario, this new force can be introduced by extending the gauge group of the Standard Model of Particle Physics with a new abelian U(1) gauge symmetry. The corresponding new spin-1 gauge boson (i.e., the dark photon) can then couple very weakly to electrically charged particles through kinetic mixing with the ordinary photon[2] and could thus be detected. The dark photon can also interact with the Standard Model if some of the fermions are charged under the new abelian group.[3] The possible charging arrangements are restricted by a number of consistency requirements such as anomaly cancellation and constraints coming from Yukawa matrices.

Answer 2

Dark photon particles

• Photons are defined as energy packets that can emerge from any source. They are defined as energy packets emitted from a source of electromagnetic radiation.

• The heavier particle's existence also revealed, and transporter of invisible forces to our eyes.
• This particle is known as a dark photon, and it is linked to the presence of dark matter. They have qualities comparable to photons but are invisible.
