Available in PDF, EPUB and Kindle. Book excerpt: We present the results of a search for four exclusive semileptonic decays B → D{sup (*)}[tau]−{bar [nu]}{sub [tau]} in 209 fb−1 of data collected with the BABAR detector, corresponding to 232 million e+e- → [Upsilon](4S) → B{bar B} events. We select events with a D{sup (*)} meson and a light lepton (e or [mu]) recoiling against a fully-reconstructed B meson. We perform a fit to the lepton spectrum and missing mass squared to discriminate signal events from backgrounds, predominantly B → D{sup (*)}{tau}−{bar [nu]}{sub {tau}}. A control sample of identified D**l−{bar {nu}}{sub {ell}} events is included in the fit to estimate the background contribution from these decays. We measure [beta](B → D{sub {tau}{nu}}) = (0.86±0.24±0.11±0.06)% and [beta](B → D*{sub {tau}{nu}}) = (1.62±0.31±0.10±0.05)%, where the errors are statistical, systematic, and normalization-mode related, respectively, and where the results are expressed for the {bar B}° lifetime.

Download or read book Gauge Theory of Weak Decays written by Andrzej J. Buras and published by Cambridge University Press. This book was released on 2020-07-02 with total page 739 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The ultimate question of elementary particle physics is: What is the fundamental Lagrangian of nature surrounding us? The Lagrangian of the SM is very successful in describing nature at the currently available energy range. The discovery of the Higgs boson completed the particle spectrum of the SM and it is another proof of how well the SM works. Nevertheless the SM cannot be the end of the story and it is for sure not the fundamental Lagrangian of nature. The Lagrangian of the SM looses its validity at the latest at the Planck scale where gravitational effects become noticeable.Most physicists think of the SM as an effective theory that has to be replaced by a more fundamental theory above the TeV scale. What the word effective really means will hopefully be clear at later stages of our book. For the time being we will list some problems and open questions of the SM"--

Download or read book Heavy Flavours and High-Energy Collisions in the 1–100 TeV Range written by A. Ali and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume is based on the proceedings of the 6th and 7th INFN ELOISATRON project workshops, held at the Centro di Cultura Scientifica "Et tore Majorana" CCSEM, Erice-Trapani, Sicily, Italy, in the period June 10-27, 1988. The topics of the two workshops were, respectively: - Heavy Flavours: Status and Perspectives, and - Novel Features of High Energy Collisions in 1-100 TeV Region. They were attended by sixty-three physicists. The two workshops were followed by a meeting of the INFN ELOISATRON working group, also held at the CCSEM in the period October 7-15, 1988 in which twenty-five physicists participated. Since there was quite a bit of overlap among speakers, participants and the topics covered at the three meetings, we have decided to issue ajoint proceeding, with the first part entitled: Heavy Flavour Physics, and the second: High Energy Physics with 1-100 Te V Proton Beams. Some of the reports included in this volume have been contributed by the INFN ELOISATRON working group members. The first. part of these proceedings deals mostly with the presentation and inter pretation of results in t.he so-called fiavour physics sector. New results, which have become available in the last three years from experiments involving kaons, charmed and beauty hadrons, and searches for the still missing top quark at the present and fothcoming colliders are topics of major interest. here. The contributions in this part are organized in three categories: Experimental Results, Theoretical Interpretation, and Future Directions.

Download or read book Heavy Meson Observables and Dyson Schwinger Equations written by and published by . This book was released on 1998 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dyson-Schwinger equation (DSE) studies show that the b-quark mass-function is approximately constant, and that this is true to a lesser extent for the c-quark. This observation provides the basis for a study of the leptonic and semileptonic decays of heavy pseudoscalar mesons using a ''heavy-quark'' limit of the DSES, which, when exact, reduces the number of independent form factors. Semileptonic decays with light mesons in the final state are also accessible because the DSES provide a description of light-quark propagation characteristics and light-meson structure. A description of B-meson decays is straightforward, however, the study of decays involving the D-meson indicates that c-quark mass-corrections are quantitatively important.

Book excerpt: These lectures are intended to provide an introduction to heavy meson decays and CP violation. The first lecture contains a brief review of the standard model and how the CKM matrix and CP violation arise, mixing and CP violation in neutral meson systems, and explanation of the cleanliness of the sin 2[beta] measurement. The second lecture deals with the heavy quark limit, some applications of heavy quark symmetry and the operator product expansion for exclusive and inclusive semileptonic B decays. The third lecture concerns with theoretically clean CP violation measurements that may become possible in the future, and some developments toward a better understanding of nonleptonic B decays. The conclusions include a subjective best buy list for the near future.

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.
