		In physics, a meson is a non-elementary particle (hadron) composed of a quark and an antiquark of opposite color charge.
		Pseudoscalar mesons (spin 0) have the lowest energy, where the quark and antiquark have opposite spin, and then the vector mesons (spin 1), where the quark and antiquark have parallel spin.
		Mesons were originally predicted as carriers of the force that bind protons and neutrons together.

		In particle physics, a meson is a strongly interacting boson, that is, it is a hadron with integral spin.
		Until the discovery of the tetraquark, all known mesons were believed to consist of a quark-antiquark pair - the so-called valence quarks - plus a "sea" of virtual quark-antiquark pairs and virtual gluons.
		Pseudoscalar mesons (spin 0) have the lowest rest energy, where the quark and antiquark have opposite spin, and then the vector mesons (spin 1), where the quark and antiquark have parallel spin.
