Linked from

The 15 pages that link to CPT symmetry, each with the reason it gives.

• CP violationRelated: CP violation does not by itself imply CPT violation.

• AntimatterRelated: It underlies the predicted relationship between particles and antiparticles.

• AntiparticleRelated: It underlies the expectation that particles and antiparticles have equal masses and lifetimes.

• AntiprotonRelated: It predicts matching proton and antiproton masses and lifetimes.

• Matter–antimatter asymmetryRelated: CPT symmetry constrains how matter and antimatter properties can differ despite cosmic abundance imbalance.

• Time-reversal symmetryRelated: CPT can remain conserved even when time reversal alone is violated.

• Sakharov conditionsRelated: CPT invariance links CP violation to the nonequilibrium dynamics relevant to generating an asymmetry.

• AntihydrogenRelated: Comparing hydrogen and antihydrogen spectra tests this fundamental symmetry.

• Neutral kaonRelated: Comparing neutral-kaon properties tests stringent consequences of this symmetry.

• Norman Ramsey Jr.Related: Ramsey’s experiments on atomic and molecular systems contributed to stringent tests of fundamental symmetry.

• Symmetry-based models (mathematical physics)Related: Its status probes deep links among locality, Lorentz invariance, and quantum field theory.
