CPT Theorem

All physical laws are invariant under simultaneous charge conjugation, parity, and time reversal.

Core Principles & Analysis

• Proved in the mid-1950s by Gerhart Lüders and Wolfgang Pauli.
• Implies particles and antiparticles have identical masses and lifetimes.
• Holds in any local, Lorentz-invariant quantum field theory, and no violation has ever been observed.
