摘要：
We extend the 5-dimensional Galilean space-time to a (5 + 1) Galilean space-time in order to define a parity transformation in a covariant manner. This allows us to discuss the discrete symmetries in the Galilean space-time, which is embedded in the (5 + 1) Minkowski space-time. We discuss the Dirac-type field, for which we give the 8 x 8 gamma matrices explicitly. We demonstrate that the CPT theorem holds in the (5 + 1) Galilean space-time. (c) 2008 Elsevier B.V.
