Book Description
Using a subset of data collected in the 1996-97 fixed target run at Fermilab, the authors report the first preliminary measurement on the direct-CP violation from the KTeV experiment. The result is, e'/e = (28.0-4.1) x 10−4, nearly 7 standard deviations above zero obtained by a blind analysis. This establishes the long-sought direct-CP violation effect in the two-pion system of neutral kaon decays. The experimental technique, data analysis and systematic checks for this measurement are discussed and the comparison with other measurements is also presented.

Book Description
We report the first KTeV measurement for the search of direct-CP violation by using 23% of the data sample collected in the 1996-97 fixed target run at Fermilab. The result is, Re([epsilon][prime]/[epsilon])= (28.0[+-] 4.1) x 10[sup -4], nearly 7[delta] above zero obtained by a blind analysis. This firmly establishes the long-sought ''direct-CP violation'' effect in the two-pion system ([pi][sup+][pi][sup -] versus[pi][sup 0][pi][sup 0]) of neutral kaon decays. Other new measurements of[Delta]m, [tau][sub s], [Delta][phi] and a limit on the diurnal variation of[phi][sub+-] for testing CPT invariance from the same data sample are also presented.

Book Description
The authors present an updated search for direct CP violation in the decay B[sup 0] --> K[sup +]pi[sup -]. Using 227 million [Upsilon](4S) --> B[bar B] decays collected with the BaBar detector at the PEP-II asymmetric-energy E[sup +]e[sup -] collider at SLAC, the authors observe a total signal yield of n(K-pi[sup +]) + n(K[sup +]pi[sup -]) = 1606 [+-] 51 decays and measure the asymmetry [n(K[sup -]pi[sup +])-n(K[sup +]pi[sup -])]/[n(K[sup -]pi[sup +])+n(K[sup +]pi[sup -])] = 0.133 [+-] 0.030(stat) [+-] 0.009(syst). This measurement establishes direct CP violation in the B[sup 0] meson system at the level of 4.2 standard deviations.
