meson

(two-quark particles)

A meson is a composite particle comprised of two quarks, generally a quark and an antiquark (antimatter equivalent).


Note that at some point in its history, particle physics refined the definition of a meson as more was learned, such that some particles no longer fit the definition. For example, before this change, the muon was considered a type of meson.
