Ghosts (physics) → Ghost (physics) – We may talk about a (Landau) ghost, singular should be the standard. MaoGo (talk) 08:40, 4 July 2018 (UTC)
- Support Agreed, singular is is fine here and preferred for titles. --
{{u|Mark viking}} {Talk}23:47, 5 July 2018 (UTC) - Support I agree that singular is better for use in titles. Also, I think the opening sentence should be revised to something like the following: "In the terminology of quantum field theory, a ghost, ghost field, or gauge ghost is an unphysical state of a gauge theory."

Too advanced
editThis seems confusingly advanced and not understandable for most people. I think there’s a template for it, but I’m not sure the exact template Pokeswap (talk) 12:08, 18 May 2020 (UTC)
- @Pokeswap: maybe you are looking for this Template:Technical, yet I would advise against it, this is indeed a technical subject that it is already advanced for the average physicist that does not do high energy physics.--ReyHahn (talk) 13:10, 18 May 2020 (UTC)
Electromagnetism and ghosts
editThe article states ‘An example of the need of ghost fields is the photon, which is usually described by a four component vector potential Aμ, even if light has only two allowed polarizations in the vacuum.’
Electromagnetism does not require a ghost field. The restriction to two polarisation directions van be understood without resorting to this technique. Aoosten (talk) 09:33, 10 December 2023 (UTC)
