“strangeness”的概念、定义、习题解题方法及翻译-物理辞典

单词	strangeness
释义	strangeness Symbol s. A property of certain elementary particles called hadrons (K-mesons and hyperons) that decay more slowly than would have been expected from the large amount of energy released in the process. These particles were assigned the quantum number s to account for this behaviour. For nucleons and other nonstrange particles s = 0 ; for strange particles s does not equal zero but has an integral value. In quark theory (see elementary particles) hadrons with the property of strangeness contain a strange quark or its antiquark
