The 28 pages that link to CP violation, each with the reason it gives.
MesonRelated: Neutral kaon decays revealed CP violation in particle physics.
AntiparticleRelated: It provides one ingredient that may help explain the cosmic matter excess.
KaonRelated: Neutral-kaon decays provided the first observed evidence that CP symmetry is violated.
Time-reversal symmetryRelated: Under CPT symmetry, CP violation entails time-reversal violation.
LeptogenesisRelated: Unequal decay rates into leptons and antileptons require CP violation.
HyperonRelated: Hyperon decays offer tests of CP violation in baryon systems.
B − LRelated: It is a separate ingredient in matter-generation scenarios, not a definition of B − L.
