Conservation of parity would not allow both systems to come from a single particle. But what if Wigner’s parity theory were wrong? The K mesons were produced during weak force interactions when ...

Conservation rules and symmetries. Parity Conservation and intrinsic parity of particles. Parity violation in weak interactions. Charge conjugation invariance and its violation in weak interactions.

Wu verified the theoretical proposal that won Tsung-Dao Lee and Chen-Ning Yang the Nobel Prize in 1957 and overturned the fundamental law of physics known as parity conservation in weak interactions.
