Intrinsic parity - Wikipedia
Webtwo entirely decoupled Dirac equations. One has three intrinsic degrees of freedom, which we associate with the three colors of the quarks, and the other has one intrinsic degree of freedom, which we associate with the “single color" of the lepton. So, we write the corresponding Dirac equations as ΛµPµΦ ˜q =mΦq ΛµPµΦ ˜l =mΦl. (42) Web在粒子物理學上，夸克模型（英語： Quark Model ）是一種根據強子內價夸克種類的強子分類方案，而價夸克就是強子內的夸克和反夸克，它們是強子量子數的源頭。 夸克是“SU(3)味對稱”或八重道的基礎，這個分類方案成功將1950至60年代所發現的的大量較輕的強子妥當編 … WebJHEP01(2015)024 Published for SISSA by Springer Received: November 5, 2014 Accepted: November 26, 2014 Published: January 8, 2015 Study of η–η0 mixing from measurement of B0 (s) cheer t-shirt designs
