Conservation of isotopic spin and isotopic gauge invariance Phys.

Rev. 96, 191-195 (1954)

或者我来贴个原文的abstract:

It is pointed out that the usual principle of invariance under isotopic spin

rotation is not consistent with the concept of localized fields. The

possibility is explored of having invariance under local isotopic spin

rotations.This leads to formulating a principle of isotopic gauge invariance

and the existence of a ь field which has the same relation to the isotopic

spin that the electromagnetic field has to the electric charge. The ь field

satisfies nonlinear differential equations. The quanta of the ь field are

particles with spin unity, isotopic spin unity, and electric charge +/- e or

zero.

规范场物理意义是什么，这是很清楚的事。重要的是，文中提了非阿贝尔规范对称来写出相互作用这个方法。

拜托诸位如果要骂杨振宁的物理成就时，可不可以先不耻下问一下你们物理系的朋友？

看到有些帖子，我真的很痛心疾首，这是在作践我们物理人的儿女啊
