Description
CPT violation has an impressive limit in the neutral kaon system vertical bar m(K0)-m(K-bar 0) vertical bar 10-18mK=0.50x10-18 GeV. However, if viewed as a constraint on the mass-squared, the bound appears weak, vertical bar m2(K0)-m2(K-bar 0) vertical bar 0.25 eV2. We point out that neutrino oscillation offers better limits on CPT violation in this case. The comparison of solar and rector neutrino results puts the best limit on CPT violation by far, vertical bar Δmν2-Δmν-bar 2 vertical bar 1.3x10-3 eV2 (90% CL)
