Abstract

We make use of high-precision measurements in the neutral kaon system to analyze how well CPT is conserved. Although present data provide rather stringent tests of CPT, actually these measurements provide bounds only on differences of CPT-violating parameters. Although CP-violating phenomena in the DELTA-S = 2 sector are dominantly CPT conserving, present data do not allow a similar unambiguous statement to be made for the DELTA-S = 1 sector.
