meson | boson | Bose-Einstein statistics | 2 | 0 | uncertainty principle | A strongly interacting particle consisting of a quark and an antiquark. Its mass is intermediate between that of a proton and an electron, which is believed to be responsible for the strong nuclear force. In contrast to the case of baryons or leptons, meson number is not conserved: like photons, mesons can be created or destroyed in arbitrary numbers. |
