正则旋量场的等价性

Equivalence of regular spinor fields

Cheng-Yang Lee

AI总结:

本文从Lounesto分类的三类正则旋量构造了局域且Lorentz协变的费米子场,通过计算不变量和双线性协变量,证明它们在物理上等价于Dirac场。

摘要:

在Lounesto分类中,有三类正则旋量。它们的分类条件是标量或赝标量范数中至少有一个非零。Dirac旋量是正则旋量,因为其标量和赝标量范数分别为非零和零。我们从所有三类正则旋量构造了局域且Lorentz协变的费米子场。通过计算正则旋量场的不变量和双线性协变量,我们证明了它们在物理上等价于Dirac场,即无论用正则旋量场写出何种相互作用,总可以用Dirac场来表示。

英文摘要:

In the Lounesto classification, there are three types of regular spinors. They are classified by the condition that at least one of the scalar or pseudo scalar norms are non-vanishing. The Dirac spinors are regular spinors because their scalar and pseudo scalar norms are non-zero and zero respectively. We construct local and Lorentz-covariant fermionic fields from all three classes of regular spinors. By computing the invariants and bilinear covariants of the regular spinor fields, we show that they are physically equivalent to the Dirac fields in the sense that whatever interactions one writes down using the regular spinor fields, they can always be expressed in terms of the Dirac fields.
