charge conjugation quantum number edit

Originally proposed at Wikidata:Property proposal/Natural science

Done: charge conjugation quantum number (P7527) (Talk and documentation)

Description	charge conjugation (or c-parity) has a multiplicative quantum number that applies when all quantum charges are reversed, i.e. when a particle is transformed into its antiparticle
Represents	C parity (Q16251327)
Data type	Quantity
Template parameter	"c_parity" in en:template:infobox particle
Domain	type of quantum particle (Q22675015)
Allowed values	1,-1
Example 1	photon (Q3198) → -1
Example 2	π⁰ (Q17254284) → +1
Source	en:C parity, Review of Particle Physics (2018), [1]
Planned use	Improve particle items with data from Review of Particle Physics (Q56810046).
Expected completeness	eventually complete (Q21873974)
See also	parity quantum number (P1123)

Motivation edit

Basically the description: I want to add data about charge conjugation to items about quantum particles. Sarilho1 (talk) 16:08, 30 October 2019 (UTC)[reply]

Discussion edit

Notified participants of WikiProject Physics I choose this name because I think it is clearer than C-parity and I'm not familiar with usage of the later, though, following the Wikipedia page, it should be correct too, if you prefer. I only provided two examples, because items for several particles are still lacking: K0, eta0, etc. K0, in particular, should be a good third example to add, once created. - Sarilho1 (talk) 16:19, 30 October 2019 (UTC)[reply]
