Precise comparisons of the fundamental properties of matter–antimatter conjugates provide sensitive tests of charge–parity–time (CPT) invariance, which is an important symmetry that rests on basic assumptions of the standard model of particle physics. Experiments on mesons, leptons and baryons have compared different properties of matter–antimatter conjugates with fractional uncertainties at the parts-per-billion level or better. One specific quantity, however, has so far only been known to a… 

A 16-parts-per-trillion measurement of the antiproton-to-proton charge–mass ratio

A new comparison of the proton/antiproton charge-to-mass ratios with a fractional uncertainty of 16 parts per trillion is reported, consistent with the fundamental charge–parity–time reversal invariance, and improves the precision of the previous best measurement by a factor of 4.3.

The riddle of the baryon asymmetry, i.e. the matter antimatter imbalance in the universe can be addressed by comparing matter particles with their antimatter counterparts. At the antiproton

Characterization of the 1S–2S transition in antihydrogen

The shape of the spectral line and the resonance frequency of the 1S–2S transition in antihydrogen agree very well with those of hydrogen, consistent with charge–parity–time invariance at a relative precision of 2 × 10−12—two orders of magnitude more precise than the previous determination.
