Popis: The CPLEAR experiment at CERN studies the CP, T and CPT symmetries in the neutral-kaon system by measuring the rate asymmetries between the decays of initially pure K-0 and (K-0) over bar states. Using data taken between 1900 and mid 1994, precise measurements of η(+ -) phi(+ -) and Delta m are reported. The comparison of phi(+ -) with the superweak phase gives one of the most sensitive tests of CPT invariance and leads to a new limit on the K-0-(K-0) over bar mass difference.
