The invariance of classical electromagnetism under Charge-conjugation, Parity and Time-reversal (CPT) transformations

摘要

The invariance of classical electromagnetism under charge-conjugation, parity, and time-reversal (CPT) is studied by considering the motion of a charged particle in electric and magnetic fields. Upon applying CPT transformations to various physical quantities and noting that the motion still behaves physically demonstrates invariance.
