Languages : en
Pages : 7
Book Description
The authors present a measurement of relative partial widths and decay rate CP asymmetries in K−K and?−?+ decays of D° mesons produced in p{bar p} collisions at √s = 1.96 TeV. They use a sample of 2 x 105 D*+ → D°?+ (and charge conjugate) decays with the D° decaying to K−?+, K−K+, and?−?+, corresponding to 123 pb−1 of data collected by the CDF II experiment at the Fermilab Tevatron collider. No significant direct CP violation is observed, they measure?(D° → K−K+)/?(D° → K−?+) = 0.0992 ± 0.0011 ± 0.0012,?(D° →?−?+)/?(D° → K−?+) = 0.03594 ± 0.00054 ± 0.00040,?(D° → K−K+)/?(D° →?−?+) = 2.760 ± 0.040 ± 0.034, A{sub CP} (K−K+) = (2.0 ± 1.2 ± 0.6)%, and A{sub CP}(?−?+) = (1.0 ± 1.3 ± 0.6)%, where, in all cases, the first uncertainty is statistical and the second is systematic.

Book Description
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.

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.

Using 227 million [Upsilon](4S) --> B{bar B} decays collected with the BaBar detector at the PEP-II asymmetric-energy Ee− collider at SLAC, the authors observe a total signal yield of n(K-pi+) + n(K+pi−) = 1606 ± 51 decays and measure the asymmetry [n(K−pi+)-n(K+pi−)]/[n(K−pi+)+n(K+pi−)] = 0.133 ± 0.030(stat) ± 0.009(syst). This measurement establishes direct CP violation in the B° meson system at the level of 4.2 standard deviations.
