详细了解必应搜索结果 此处Hadronic subatomic particle组织和汇总搜索结果A meson is a type of hadronic subatomic particle composed of an equal number of quarks and antiquarks. It is a fundamental particle categorized under the hadrons. Mesons are sensitive to the strong force, the fundamental interaction that binds the components of the nucleus by governing the behaviour of their constituent quarks. Mesons are the interaction agents between nucleons (protons and electrons). The rest mass of the mesons lies between 250-100mₑ.4 来源

In particle physics, a meson is a type of hadronic subatomic particle composed of an equal number of quarks and antiquarks, usually one of each, bound together by the strong interaction. Because mesons are composed of quark subparticles, they have a meaningful physical size, a diameter of roughly one femtometre (10 … 展开
From theoretical considerations, in 1934 Hideki Yukawa predicted the existence and the approximate mass of the "meson" as the carrier of the nuclear force that holds atomic … 展开
Mesons are classified into groups according to their isospin (I), total angular momentum (J), parity (P), G-parity (G) or C-parity (C) when applicable, and quark (q) content. The rules for classification are defined by the Particle Data Group, and are rather convoluted. … 展开
