CPT symmetry, a fundamental principle in quantum field theory, asserts that the laws of physics remain invariant under the combined transformations of charge conjugation (C), parity transformation (P), and time reversal (T). The CPT Theorem, also known as Lüder's Theorem, is rigorously derived from the assumptions of locality and Lorentz invariance. Evidence supporting CPT symmetry is discussed in Weinberg's "The Quantum Theory of Fields," Vol 1, p 245. Experimental searches for violations of CPT symmetry have been conducted, highlighting its significance in theoretical physics.
