Past electron-positron g-2 experiments yielded sharpest bound on CPT violation for point particles

In our experiments on a single e(-) and e(+) we measured the cyclotron and spin-cyclotron difference frequencies omega(c)(+/-) and omega(a)(+/-) = omega(s)(+/-) - omega(c)(+/-) and ratios a(+/-) = omega(a)(+/-)/omega(c)(+/-) at omega(c)/2 pi similar or equal to 141 GHz and e(-) values also at omega(c)/2 pi similar or equal to 164 GHz. Here we do extract from these data a new figure of merit for violation of CPT symmetry similar to \m(Kaon) - m(Antikaon)\/m(Kaon) less than or similar to 10(-18) for the K mesons composed of two quarks. That expression compares experimental relativistic mass energies of particle states before and after the C, P, T operations have transformed particle into antiparticle. The figure for our noncomposite leptons was even smaller: \(h) over bar(omega(a)(+)/2) - (h) over bar(omega(a)(+)/2)\/m(0)c(2) less than or similar to 12 X 10(-22).
