The authors present measurements of time-dependent CP-violation asymmetries for the decays B{sup 0} {yields} {eta}'K{sup 0}. The data sample corresponds to 347 million B{bar B} pairs produced by e{sup +}e{sup -} annihilation at the {Upsilon}(4S) resonance in the PEP-II collider, and collected with the BABAR detector. The preliminary results are S = 0.55 {+-} 0.11 {+-} 0.02, and C = -0.015 {+-} 0.07 {+-} 0.03, where the first error quoted is statistical, the second systematic.

Download Measurement of Time-dependent CP Violation in B0 2![eta]'K0 Decays Book in PDF, ePub and Kindle
We present a measurement of the time-dependent CP violation parameters in B0 2![eta]'K0 decays. The measurement is based on the full data sample containing 772×106 BB-bar pairs collected at the [Upsilon](4S) resonance using the Belle detector at the KEKB asymmetric-energy e+e- collider. The measured values of the mixing-induced and direct CP violation parameters are: sin 2[phi]1eff = +0.68 " 0.07 " 0.03, A[eta]'K0 = +0.03 " 0.05 " 0.04, where the first uncertainty is statistical and the second is systematic. The values obtained are the most accurate to date. Furthermore, these results are consistent with our previous measurements and with the world-average value of sin 2[phi]1 measured in B0 2!J/[psi]K0 decays.

Download Measurement of Time-Dependent CP-Violating Asymmetries in B° Meson Decays to Eta' K° Book in PDF, ePub and Kindle
The authors present a preliminary measurement of CP-violating parameters S and C from fits of the time-dependence of B° meson decays to [eta]'K°. The data were recorded with the BABAR detector at PEP-II and correspond to 227 x 106 B{bar B} pairs produced in ee− annihilation through the [Upsilon](4S) resonance. From a maximum likelihood fit they measure the CP-violation parameters S = 0.27 ± 0.14 (stat.) ± 0.03 (syst.) and C = -0.21 ± 0.10 (stat.) ± 0.03 (syst.).

This thesis describes a high-quality, high-precision method for the data analysis of an interesting elementary particle reaction. The data was collected at the Japanese B-meson factory KEKB with the Belle detector, one of the most successful large-scale experiments worldwide. CP violation is a subtle quantum effect that makes the world look different when simultaneously left and right and matter and antimatter are exchanged. This being a prerequisite for our own world to have developed from the big bang, there are only a few experimental indications of such effects, and their detection requires very intricate techniques. The discovery of CP violation in B meson decays garnered Kobayashi and Maskawa, who had predicted these findings as early as 1973, the 2008 Nobel prize in physics. This thesis describes in great detail what are by far the best measurements of branching ratios and CP violation parameters in two special reactions with two charm mesons in the final state. It presents an in-depth but accessible overview of the theory, phenomenology, experimental setup, data collection, Monte Carlo simulations, (blind) statistical data analysis, and systematic uncertainty studies.

Download Observation of CP Violation in B^0 to Eta' K^0 Book in PDF, ePub and Kindle
The authors present measurements of the time-dependent CP-violation parameters S and C in B° 2!K° decays. The data sample corresponds to 384 million B{bar B} pairs produced by ee− annihilation at the [Upsilon](4S). The results are S = 0.58 ± 0.10 ± 0.03, and C = -0.16 ± 0.07 ± 0.03. They observe mixing-induced CP violation with a significance of 5.5 standard deviations in this b 2!s penguin dominated mode.

Keywords:CP Violation;Quark Mixing Matrix;Charm Decays;B Decays;Nonleptic Interactions;Heavy QuarksReview: “Similar material is most often available in journals, but the book accomplishes a valuable service in drawing it together … the one that will probably have the greatest utility and longest lifespan is the survey of B meson physics by I Bigi, V Khoze, N Uraltsev and A Sanda … Bigi et al. here provide the most thorough and readable account of the issues that I know of. I have seen no review comparable to the excellent summary of electric dipole moments by S Barr and W Marciano … the volume offers a generally readable entry into this field for a reader who has a basic background in particle physics.” John F Donoghue Science “… this book performs a very useful service for anyone active or interested in CP violation, both as a source of primary information and as a work of reference.” K J Peach J Phys.
