# Commutations relations of C,P,T transformations with Lorentz group

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.

• Weinberg covers this, of course. – Oбжорoв Jan 8 '20 at 15:13
• @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. – MKO Jan 8 '20 at 17:26
• Volume chapter 2 if my recollection is correct. – Oбжорoв Jan 8 '20 at 18:35

Weinberg vol 1 Eqs (2.6.7) to (2.6.12) for $$P$$ and $$T$$.
