A determination of the CP violation parameter eta(+-) from the decay of
strangeness-tagged neutral kaons

Αγγλικά

{We report a measurement of the CP violation parameter eta(+-) from the
time-dependent asymmetry between the decay rates of initially tagged K-0
and (K) over bar(0). The results are based on the complete data sample
collected by the CPLEAR collaboration. With Delta m = (530.1 +/- 1.4) X
10(7)(h) over bar s(-1) and tau(S) = (89.34 +/- 0.08) ps, the values
obtained are \textbackslash{}eta(+-)\textbackslash{} = (2.264 +/-
0.023(stat) +/- 0.026(syst) +/- 0.007 tau(s)) x 10(-3) and phi(+-) =
43.19 degrees +/- 0.53(stat)degrees +/- 0.28(syst)degrees + 0.42(Delta
m)degrees. (C) 1999 Published by Elsevier Science B.V. All rights
