Available in PDF, EPUB and Kindle. Book excerpt: A search for the rare decays of B0 [RIGHTWARDS ARROW] [MICRO SIGN]+ [MICRO SIGN][-] and B0 [RIGHTWARDS ARROW] [MICRO SIGN]+ [MICRO SIGN][-] is presented in p p collis d [SQUARE ROOT] sions at s=1.96 TeV corresponding to 10 fb[-]1 of integrated luminosity collected by the CDF II detector. The observed number of B0 candidates is consistent with d background-only expectations and yields an upper limit on the branching fraction B(B0 [RIGHTWARDS ARROW] [MICRO SIGN]+ [MICRO SIGN][-]) of 4.2 x 10[-]9 at 95% confidence level. An excess is observed d for the B0 signal region. The probability that background processes alone could s produce such an excess or larger is 0.94%. The probability that the combination of background and the expected standard model rate B0 [RIGHTWARDS ARROW] [MICRO SIGN]+ [MICRO SIGN][-] could produce s such an excess or larger is 6.8%. These data are used to determine a central value of B(B0 [RIGHTWARDS ARROW] [MICRO SIGN]+ [MICRO SIGN][-]) = (1.3+0.9) x 10[-]8 as well as a two sided limit at 90% C.L. s [-]0 7 of 2.2 x 10[-]9

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.

Book excerpt: This volume is a collection of review articles on the most outstanding topics in heavy flavour physics. All the authors have made significant contributions to this field. The book reviews in detail the theoretical structure of heavy flavour physics within the Standard Model and its confrontation with existing experimental data.The physics of the top quark and of the Higgs play an important role in this volume. Beginning with radiative electroweak corrections and their impressive tests at LEP and hadron colliders, the book summarizes the present status of quark mixing, CP violation and rare decays. The dynamics of exclusive D- and B-meson decays, the τ-lepton physics and the newly discovered heavy quark symmetries are discussed in detail. The impact of strong interactions on weak decays is clearly visible in many articles. The physics of heavy flavours at LEP, HERA and hadron colliders constitutes an important part of the book. Another significant topic is the possible role of heavy flavours in the spontaneous symmetry breaking of gauge symmetries. Finally the most recent advances in lattice calculations of the properties of heavy flavours and the lattice studies of the dynamics of heavy flavours are presented.

Available in PDF, EPUB and Kindle. Book excerpt: CERN, the European Laboratory for particle physics, regularly makes the news. What kind of research happens at this international laboratory and how does it impact people's daily lives? Why is the discovery of the Higgs boson so important? Particle physics describes all matter found on Earth, in stars and all galaxies but it also tries to go beyond what is known to describe dark matter, a form of matter five times more prevalent than the known, regular matter. How do we know this mysterious dark matter exists and is there a chance it will be discovered soon? About sixty countries contributed to the construction of the gigantic Large Hadron Collider (LHC) at CERN and its immense detectors. Dive in to discover how international teams of researchers work together to push scientific knowledge forward. Here is a book written for every person who wishes to learn a little more about particle physics, without requiring prior scientific knowledge. It starts from the basics to build a solid understanding of current research in particle physics. A good dose of curiosity is all one will need to discover a whole world that spans from the infinitesimally small and stretches to the infinitely large, and where imminent discoveries could mark the dawn of a huge revolution in the current conception of the material world.
