Bearing in mind the Lounesto spinor classification, we connect the expansion coefficients of well behaved fermionic quantum field, i.e., a local field within a full Lorentz covariant theory, with and only with a given subclass of Type-2 spinors according to Lounesto. We comment on theoretical possibilities as well as physical outputs for the other cases.

规则的旋子和费米子场

考虑到Lounesto旋子的分类，我们将行为良好的铁离子量子场（即完整的Lorentz协变理论中的局部场）的膨胀系数与根据Lounesto的给定子类型2旋子连接在一起。我们对其他情况的理论可能性以及实际产出进行评论。
