magnetic photon

{{Short description|Hypothetical particle}}

In physics, a magnetic photon is a hypothetical particle. It is a mixture of even and odd C-parity states and, unlike the normal photon, does not couple to leptons. It is predicted by certain extensions of electromagnetism to include magnetic monopoles. There is no experimental evidence for the existence of this particle, and several versions{{Cite journal |arxiv = hep-ph/9708394|doi = 10.1142/S0217732397003277|title = A Model of Magnetic Monopoles|journal = Modern Physics Letters A|volume = 12|issue = 40|pages = 3153–3159|year = 1997|last1 = Kühne|first1 = Rainer W.| bibcode=1997MPLA...12.3153K | s2cid=204007639 }} have been ruled out by negative experiments.{{Cite journal |arxiv = physics/0405148|doi = 10.1016/j.physleta.2004.07.028|title = Experimental test of magnetic photons|journal = Physics Letters A|volume = 329|issue = 4–5|pages = 298–300|year = 2004|last1 = Lakes|first1 = R.

The magnetic photon was predicted in 1966 by the Nobel Prize in Physics laureate Abdus Salam.{{cite journal | last=Salam |first=A. | title= Magnetic monopole and two photon theories of C-violation | journal=Physics Letters | volume=22 | year=1966 | pages= 683–684 | doi= 10.1016/0031-9163(66)90704-9|bibcode = 1966PhL....22..683S | issue=5 }}
