Abstract

The CPLEAR experiment is aiming at precise CP violation tests using initially pure K0- and K0BAR beams from the intense source provided by the annihilation of the LEAR pBAR-beam in hydrogen. The strangeness tagging efficiency and the systematic errors have been studied and foundto be in agreement with the design specifications. The measurement ofthe differential time asymmetry of the pi+pi- decays allowed the direct observation of differences in the decay rates of particles and antiparticles.The CP violating parameters were determined as \eta+/-\ = (2.32 +/- 0.14) . 10(-3) and phi+/- = 42.3-degrees +/- 4.4-degrees. First results in the reconstruction and analysis of the neutral kaon decays into two neutral pions and the K(e)3 decay are presented.
