Almost any QFT textbook discusses the C,P,T symmetry operators which are charge conjugation, parity transformation, time reversal respectively.

I failed so far to find any discussion of the commutation relations of these operators with the Lorentz group (or its generators). I would be happy to have a reference.

  • $\begingroup$ @Oбжорoв: Could you please refer to the exact place in Weinberg's book where he computes the commutation relations between charge conjugation and a boost. $\endgroup$
