The Standard Model (SM) of particle physics, being a local, unitary and Lorentz-invariant quantum field theory, remains symmetric under the combined action of Charge, Parity, and Time Reversal (CPT) symmetry. This automatically implies that fundamental properties of particles and antiparticles should be equal in magnitude. While there are numerous experiments testing CPT symmetry, it is not clear how these tests are related with one another, and hence, if there is a reasonable way to compare bounds arising from them.
