Download or read book Leptonic and Semileptonic Decay of B and D Mesons written by Krishna Kingkar Pathak and published by LAP Lambert Academic Publishing. This book was released on 2014-11-18 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with an introductory idea of Leptonic and semileptonic decay of Heavy-Light mesons. It also highlight the application of a specific QCD potential model in this area of physics. Specifically, it also addresses the application of quantum mechanical perturbation method and explicitly the Dalagarno method of perturbation in this context. The necessity of modification of the model within the constraints of QCD and the model itself is explained and also improved accordingly. Out of the five chapters, the second and third chapters address the leptonic decay of B and D mesons whereas in the last two chapters, the study of semileptonic decay in terms of the universal form factor, Isgur-Wise function is well explained.

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: 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 Measurement of the B and B° Lifetimes from Semileptonic Decays at SLD. written by and published by . This book was released on 1996 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lifetimes of B and B° mesons have been measured using a sample of 150,000 hadronic Z° decays collected by the SLD experiment at the SLC between 1993 and 1995. The analysis identifies the semileptonic decays of B mesons with high (p, p{sub t}) leptons and reconstructs the B meson decay length and charge by vertexing the lepton with a partially reconstructed D meson. This method results in a sample of 634 (584) charged (neutral) decays with high charge purity. A maximum likelihood fit finds: [tau]{sub B{sup +}} = 1.60{sub -0.11}{sup +0.12}(stat) ± 0.06(syst) ps, [tau]{sub B{sup 0}} = 1.55{sub -0.12}{sup +0.13}(stat) ± 0.09(syst) ps, and the ratio [tau]{sub B{sup +}}/[tau]{sub B{sup 0}} = 1.03{sub -0.13}{sup +0.15}(stat) ± 0.08(syst).

Book Synopsis Semileptonic Decays of Charged D Meson Going to Eta-lepton-neutrino with Generic Reconstruction of Fully Hadronic Charged D Meson and Neutral D Meson Decays by : Richard Carl Gray
Download or read book Semileptonic Decays of Charged D Meson Going to Eta-lepton-neutrino with Generic Reconstruction of Fully Hadronic Charged D Meson and Neutral D Meson Decays written by Richard Carl Gray and published by . This book was released on 2008 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the semileptonic decays D + & rarr; eta'e+nu and D+ & rarr; etae+nu using 818 pb-1 of e+ e- collisions recorded by the CLEO-c detector located at the Cornell Electron Storage Ring. We employ a technique that uses the detector hermeticity to reconstruct the neutrino as missing energy and momentum. We improve the neutrino resolution by developing a generic algorithm to reconstruct the non-signal D, and constrain systematic uncertainties in the efficiency by using the algorithm to measure the branching fractions of D+ and D0 hadronic decays. We observe and measure the branching fractions of 67 hadronic decays, 32 of which are not listed in the PDG 2008. We find B (D+ & rarr; eta'e +nu) = (2.16 +/- 0.53 +/- 0.05 +/- 0.05) x 10-4 and B (D+ & rarr; etae +nu) = (11.7 +/- 0.98 +/- 0.34 +/- 0.26) x 10-4. Among the 67 D hadronic branching fractions observed in this analysis, we discover the decay B (D+ & rarr; pi+etaeta) = (0.34 +/- 0.06 +/- 0.032)% which is unexpectedly large considering the limited phase space available to the decay.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The time dependence of B[sub d][sup 0]-B[sub d][sup 0] mixing has been measured using a sample of 150,000 hadronic Z[sup 0] decays collected by the SLD experiment at the SLC between 1993 and 1995. The analysis identifies the semileptonic decays of B mesons with high (p, p[sub t]) leptons and reconstructs the B meson decay length and charge by vertexing the lepton with a partially reconstructed D meson. Vertex charge is used to enrich the selection of neutral over charged B mesons. This method results in a sample of 581 neutral decays with high charge purity. The B candidate is tagged at production with a combined tag that exploits the large polarized b forward-backward asymmetry in conjunction with the opposite hemisphere b jet charge. The final state is tagged by the sign of the high (p, p[sub t]) lepton. From their preliminary analysis the authors find a mass difference between the two B[sub d][sup 0] mass eigenstates of, [Delta]m[sub d]= 0.452[+-] 0.074(stat)[+-] 0.049(syst) ps[sup[minus]1].
