于是对于如上形式的拉氏量,显然我们需要加上一些项来抵消,从而达到规范不变。于是可以引入协变微分(covariant derivative):Dμϕ=∂μϕ−iAμϕ,其中Aμ是规范势(gauge potential),并且为了让协变微分确实是协变的,规范势必须满足“合适”的规范变换,则由协变微分的写出的拉氏量L=Dμϕ†Dμϕ...

推广至场论，需要引入规范势Gauge potential以处理局域规范对称性。拉格朗日量形式化为[公式]，对于复标量场，协变微分是关键，它确保了规范不变性。非阿贝尔情况下，规范势的非交换性质导致了field strength的构造，比如Yang-Mills场强度。同位旋理论中，通过扩展到N个内禀自由度，拉格朗日量和规范势矩阵化，...

非阿贝尔规范场论揭示了物理学中一个深刻的理论框架，它超越了传统的电磁理论，引入了更为丰富的数学结构。在二阶反对称的电磁场张量的背景下，我们开始探索真空无源区域中的物理现象，通过洛伦兹不变的拉格朗日量，我们得以导出经典的Maxwell方程，这些方程以4-矢量和Four-current的形式展现了物理世界的动态...

This gauge is particularly well adapted to discuss the problem of mixing of gauge-invariant operators, the latter being important for the discussion of the small distance behaviour in asymptotically free theories of strong interactions. Here we want to give a theoretical basis for calculations in ...
