Abstract

The phase factors which can appear in the definition of the inversions,C, P, T and their products are discussed. It is shown that because of the existence of « physically equivalent » Hamiltonians, the phases inC, CP, T andTP for complex fields are unmeasurable. For the remaining inversions, it is possible to construct interactions which require more general phases for complex fields than the usual ±1, ±i, when and only when the theory contains certain discrete multiplicative symmetries. Examples of such interactions are given.
