Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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(????????/?) = (28.0 ± 4.1) x 10−4, nearly 7? above zero obtained by a blind analysis. This firmly establishes the long-sought ''direct-CP violation'' effect in the two-pion system (??− versus?°?°) of neutral kaon decays. Other new measurements of?m,?{sub s},?? and a limit on the diurnal variation of?{sub +-} for testing CPT invariance from the same data sample are also presented.

Download or read book A High Sensitivity Search for CP Violating Rare K[sub L] Decays and Precision Measurement of the Direct CP Violation Parameter [epsilon][prime] written by and published by . This book was released on 1993 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fermilab experiments E731, E773, E799, and E832 are a series of experiments to investigate the physics of CP violation, CPT violation, and rare decays of the neutral kaon system. E731 finished data taking in 1988, during past year the full data set analysis was completed and yielded ([var epsilon][prime]/[var epsilon])[sub 2[pi]]=(7.4 [plus minus] 5.2 [stat] [plus minus] 2.9 [syst]) [times] 10[sup [minus]4] . The value favors a high top ark mass value within the Standard Model. E773 tests CPT violation by determining ([Delta][phi])[sub 2[pi]] with an accuracy of about 0.5[sup 0]. Data were taken during the last Fermilab Fixed Target run period between September and November 1991. It is anticipated the data analysis will be finished within a year. E799, with the primary goal of observing direct Cp Violation via searching for the rare decay K[sub L][yields] [pi][sup 0] l [sup +]l[sup [minus]] (where l = e, [mu] [nu]) took test data between November 1991 and January 1992 (Phase 1). Some preliminary results are shown here. E799 (Phase II) and E832 (a follow up experiment of E731) are scheduled to take data after the current Fermilab collider run with a new facility and detector.
