meson
Pion or kaon
A meson is a subatomic particle composed of a quark and an antiquark bound together by the strong nuclear force.
Mesons are unstable and decay rapidly, but they play a crucial role in mediating forces between protons and neutrons in atomic nuclei.
The term comes from Greek for "middle"—mesons have masses between electrons and protons.
Pions and kaons are common types of mesons studied in particle physics.
