Book excerpt: This 2nd edition is an extensive update of "B Decays?. The revisions are necessary because of the extensive amount of new data and new theoretical ideas. This book reviews what is known about b-quark decays and also looks at what can be learned in the future.The importance of this research area is increasing, as evidenced by the approval of the luminosity upgrade for CESR and the asymmetric B factories at SLAC and KEK, and the possibility of experiments at hadron colliders.The key experimental observations made thus far, measurement of the lifetimes of the different B species, B0-B0 mixing, the discovery of ?Penguin? mediated decays, and the extraction of the CKM matrix elements Vub and Vcb from semileptonic decays, as well as more mundane results, are described in great detail by the experimentalists who have been closely involved with making the measurements. Theoretical progress in understanding b-quark decays using HQET and lattice gauge techniques are described by theorists who have developed and used these techniques.Synthesizing the experimental and theoretical information, several articles discuss the implications for the ?Standard Model? and how further tests can be done using measurements of CP violation in the B system.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades the current theoretical description, the Standard Model of elementary particle physics, was solidified by many measurements as the basic theory describing fundamental particles and their interactions. It is extremely successful in explaining the high-precision data collected by experiments so far. The Standard Model includes several intrinsic parameters which have to be measured in experiments. Independent analyses of different physical processes can constrain those parameters. By combining those measurements physicists might be sensitive to physics beyond the Standard Model. If they are inconsistent it allows to get a hint on the theory that might supersede the Standard Model. The goal of the analysis presented in this thesis is to measure some of these parameters in the B{sub s} meson system. The B{sub s} meson, consisting of an anti-b and s quark, is not a pure mass eigenstate, thus allowing a B{sub s} meson to oscillate into its antiparticle via weak interacting processes. This is a general feature of any neutral meson. The history of meson mixing measurements is more then 50 years old. It was first observed in the kaon system. The oscillation in the B{sub d} system was measured very precisely by the B factories, whereas the oscillation frequency of the B{sub s} was measured with more than 5[sigma] significance last year by CDF and first evidence for mixing in the D0 system was presented only this year.

This book was released on 2010 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present measurements of the decays B[superscript +] [arrow right] [straight phi][straight phi] K [superscript +] and B[superscript o] [arrow right] [straight phi][straight phi] K [superscript o] using about 464 million BB[superscript -] pairs collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We report the branching fractions of the decays B [superscript +] [arrow right] [straight phi][straight phi] K[superscript +] and B[superscript o] [arrow right] [straight phi][straight phi] K[superscript o], and CP asymmetry in the charged B mode for [straight phi][straight phi] invariant mass below 2.85 GeV/ c 2 : [Special characters omitted.] Additionally, we measure the direct CP asymmetry in B[superscript +] [arrow right] [straight phi][straight phi] K [superscript +] for [straight phi][straight phi] invariant mass within the [eta][subcript c] resonance region ([2.94-3.02] GeV/ c 2): [Special characters omitted.] No direct CP asymmetry is observed both below the [eta][subcript c] and within the [eta][subcript c] resonance, as expected within the Standard Model. In each case the uncertainties are statistical and systematic, respectively.

Book excerpt: The author explores the possibility of using CP violation in B decays to detect the presence of physics beyond the Standard Model. He first studies the possibility of new physics in the B-[anti B] mixing amplitude. He discusses a construction to extract information about the phase and magnitude of the new physics contribution, as well as the CKM parameters in a model independent way. He points out the difficulty of carrying through this program induced by hadronic uncertainties and discrete ambiguities, and suggests additional measurements to overcome these problems. He then studies the possibility of new physics contributions to the B meson decay amplitudes. The author emphasizes the sensitivity of the B[yields][phi]K[sub S] decay to these new contributions, and explains how this sensitivity can be quantified using experimental data on SU(3) related decays. Finally, he analyzes a number of models where the B decay amplitudes are modified.
