Parity, charge-conjugation, and time-reversal violation in models of relativistic quantum field theory

Abstract

An analysis of dynamical, S-operator, and spontaneous violations of space parity P, charge conjugation C, time reversal T, and PCT operations in models of quantum field theory is presented. In particular, it is shown that P and T can be dynamically violated in P (Phi)/sub 2/ and sine-Gordon models and that P is dynamically violated in the Federbush model. An interesting example of spontaneous P violation in lambdaPhi/sup 4/ /sub 2/ theory is discussed. The connection between theta and PCT symmetries in quantum field theory is elucidated and it is shown that in some P (Phi)/sub 2/ and Federbush models, though theta remains a good symmetry, PCT symmetry is dynamically violated.
