Bosonphoton

Bosonphoton is not a standard term in mainstream physics. In some discussions, it may refer informally to a photon described as a boson, since photons are spin-1 gauge bosons of electromagnetism. More often, it is used to denote hypothetical bosonic particles that interact with photons or properties arising from photon-boson mixing in beyond-Standard-Model theories.

Theoretical context: Photons are massless gauge bosons of U(1) electromagnetism with two helicity states. In extensions of the Standard Model, new neutral bosons such as dark photons, Z' bosons, or axion-like particles can couple to photons via kinetic mixing or pseudoscalar couplings. A term like "bosonphoton" may appear in speculative or pedagogical writing to describe a boson that communicates with light, or a bound state involving a photon. However, there is no universally accepted definition or particle by that name.

Experimental status: No experimental evidence identifies a particle named "bosonphoton." Ongoing searches constrain properties of potential photon-coupled bosons, through laboratory experiments (such as light-shining-through-walls, photon regeneration, collider searches) and astrophysical observations. Studies typically specify the target particle (for example, a dark photon or an axion-like particle) rather than a generic "bosonphoton."
