Hadron Diagrams

Mesons are combinations of two quarks.

介子是由两个夸克组成的

The pseudoscalar mesons have quark and antiquark spins antialigned and zero orbital angular momentum, resulting in j=0. They have negative parity. The diagrams are plotted with strangeness on the vertical axis and isospin on the horizontal axis.

赝标量介子的夸克和反夸克自旋反平行，轨道角动量为零，因此总角动量j=0。它们具有负的宇称。图中纵轴为 strangeness，横轴为同位旋。

Mesons are combinations of two quarks.

介子是由两个夸克组成的

The vector mesons have quark and antiquark spins aligned and zero orbital angular momentum, resulting in j=1. They have negative parity. The diagrams are plotted with strangeness on the vertical axis and isospin on the horizontal axis.

矢量介子的夸克和反夸克自旋对齐，且轨道角动量为零，导致总自旋j=1。它们具有负的宇称。图中纵轴为 strangeness，横轴为同位旋。

The rho vector meson has a mass dramatically larger than the pseudoscalar pi meson which has the same quark content, illustrating the extraordinary variation of effective quark masses.

_rho矢量介子的质量明显大于具有相同夸克内容的赝标量π介子，这展示了有效夸克质量的非凡变化。
