关于费米子流的规范不变正则化
On gauge invariant regularization of fermion currents
摘要:
我们比较了Schwinger和复幂方法来构造正则化的费米子流。我们表明,虽然他们都是规范不变的,他们并不总是产生相同的结果。
英文摘要:
We compare Schwinger and complex powers methods to construct regularized fermion currents. We show that although both of them are gauge invariant they not always yield the same result.
