Meson that is a superposition of an up quark–antiquark and a down quark–antiquark pair
The omega meson (
ω
) is a flavourless meson formed from a superposition of an up quark–antiquark and a down quark–antiquark pair. It is part of the vector meson nonet[4][5] and mediates the nuclear force along with pions and rho mesons.
