... Unitarity then automatically follows for a scalar field theory generated by a real Lagrangian, provided regularization of the infinities is done by modifications of the prapagator that are such that Eqs.

The Spin-Statistics Relation and Noncommutative Quantum
... deduce the properties (αk )2 = β 2 = 1 and {αi, αj } = {αi, β} = 0. These anticommutation relations determine the representations of the operators α, β. They have to be hermitian, traceless and of even dimensionality N, N ≥4. The simplest way to satisfy these requirements is for α, β to be 4 × 4 con ...
