A test of $\mathit CPT$ invariance.

VALUE DOCUMENT ID TECN ($7.8$ $\pm8.4$) $ \times 10^{-18}$ 1 ANGELOPOULOS 1999 B RVUE 1  ANGELOPOULOS 1999B assumes only unitarity and combines CPLEAR with other results. Correlated with $({\mathit m}_{{{\mathit K}^{0}}}–{\mathit m}_{{{\overline{\mathit K}}^{0}}})/{\mathit m}_{\mathrm {average}}$ with a correlation coefficient of $-0.95$.

Conservation Laws:
