Experimental tests of CPT invariance
The CPLEAR experiment at CERN has directly studied matter and antimatter symmetries via the measurement of the time evolution of K /sup 0/ and K/sup 0/. The CPT violation parameter Re( delta ) was directly measured with a precision of a few 10/sup -4/ while Im( delta ) is determined from the Bell-St...

Sumario: | The CPLEAR experiment at CERN has directly studied matter and antimatter symmetries via the measurement of the time evolution of K /sup 0/ and K/sup 0/. The CPT violation parameter Re( delta ) was directly measured with a precision of a few 10/sup -4/ while Im( delta ) is determined from the Bell-Steinberger relation, with a precision of 10/sup -5/ The mass and decay-width equality between the K/sup 0/ and K/sup 0/ were tested down to the level of 10/sup -18/ Ge V.
