Available in PDF, EPUB and Kindle. Book excerpt: The authors present measurements of the time-dependent CP-violating asymmetries in B° → K{sub S}°K{sub S}°K{sub S}° decays based on 384 million [Upsilon](4S) → B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. They obtain the CP asymmetry parameters C = 0.02 ± 0.21 ± 0.05 and S = -0.71 ± 0.24 ± 0.04, where the first uncertainties are statistical and the second systematic. These results are consistent with standard model expectations.

Available in PDF, EPUB and Kindle. Book excerpt: We present a preliminary measurement of time-dependent CP-violating asymmetries in B° → J/[psi] K{sub S}° and B° → [psi](2S)K{sub S}° decays recorded by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The data sample consists of 9.0 fb−1 collected at the [Upsilon](4S) resonance and 0.8 fb−1 off-resonance. One of the neutral B mesons, produced in pairs at the [Upsilon](4S), is fully reconstructed. The flavor of the other neutral B meson is tagged at the time of its decay, mainly with the charge of identified leptons and kaons. A neural network tagging algorithm is used to recover events without a clear lepton or kaon tag. The time difference between the decays is determined by measuring the distance between the decay vertices. Wrong-tag probabilities and the time resolution function are measured with samples of fully-reconstructed semileptonic and hadronic neutral B final states. The value of the asymmetry amplitude, sin2[beta], is determined from a maximum likelihood fit to the time distribution of 120 tagged B° → J/[psi] K{sub S}° and B° → [psi](2S) K{sub S}° candidates to be sin2[beta] = 0.12 ± 0.37(stat) ± 0.09(syst) (preliminary).

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Using a sample of 379 million [Upsilon](4S) [right arrow] B anti-B events collected with the BABAR detector at the PEP-II B-factory, I study decays of B− [right arrow] D0K*− where K*− [right arrow] K0s[pi]−, K0s [right arrow] [pi][pi]− and D0 decays into K[pi] and CP-eigenstates. Both CP+ (KK−, [pi][pi]−) and CP- final states (K0s[pi]0, K0s[phi], K0s[omega]) are included. Using the Gronau-London-Wyler (GLW) and Atwood Dunietz-Soni (ADS) methods, CP-observables which are sensitive to the CKM angle [gamma] are measured.

Book excerpt: We present recent results from the BABAR Collaboration on radiative decays.

Available in PDF, EPUB and Kindle. Book excerpt: The authors present a preliminary measurement of the time-dependent CP asymmetry for the neutral B-meson decay into the CP = +1 final state K{sub S}{sup 0}{pi}{sup 0}{pi}{sup 0}, with K{sub S}{sup 0} {yields} {pi}{sup +}{pi}{sup -} and {pi}{sup 0} {yields} {gamma}{gamma}. They use a sample of approximately 227 million B-meson pairs recorded at the {Upsilon}(4S) resonance by the BABAR detector at the PEP-II B-Factory at SLAC. From a maximum likelihood fit they extract the mixing-induced CP-violation parameter S{sub K{sub S}{sup 0}{pi}{sup 0}{pi}{sup 0}} = 0.84 {+-} 0.71(stat) {+-} 0.08(syst) and the direct CP-violation parameter C{sub K{sub S}{sup 0}}{pi}{sup 0}{pi}{sup 0} = 0.27 {+-} 0.52(stat) {+-} 0.13(syst), where the first uncertainty is statistical and the second systematic.

Download or read book CP Violation From Quarks to Leptons written by M. Giorgi and published by IOS Press. This book was released on 2006-07-25 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a long time after the discovery in 1964, by Christenson, Cronin, Fitch and Turlay, that the long-lived neutral kaon decays both into three and into two pions, which has since been taken as proof of CP violation, successive new and more precise experiments confirmed the original evidence and provided results compatible with a phenomenological description confining the CP violation to the mixing between neutral kaons and antikaons. However the Standard Model, with three generations of quarks, linking as it does CP violation to the presence of a single non trivial phase in the Cabibbo-Kobayashi-Maskawa quark mixing matrix, implies that if CP violation exists at all, then it is a general property of weak interactions, appearing in transitions were amplitudes involving all three quark families interfere with each other, producing effects with a magnitude related to that of the CKM coefficients. This fact has stimulated an impressive amount of theoretical work leading in many cases to precise predictions. This publication reviews the field, from both the theoretical and experimental point of view, while planning for the forthcoming experimentation at LHC and considering possible new facilities for kaon, B meson and neutrino physics.
