This book was released on 2007 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using a sample of 1.85 million DD¯ mesons collected at the Psi(3770) with the CLEO-c detector, and a reconstruction method based on the full event hermeticity, we measure branching fractions and branching fraction ratios for the four exclusive semileptonic decay modes D 0 → pi-e +nu, D0 → K -e+nu, D + → pi0e+nu and, D+ → K¯0 e+nu. For the branching fractions we find B (D0 → pi- e+nu) = 0.299 +/- 0.011 +/- 0.008%, B (D0 → K -e+nu) = 3.55 +/- 0.03 +/- 0.08%, B (D+ → pi0 e+nu) = 0.371 +/- 0.022 +/- 0.013% and B (D+ → K¯ 0e+nu) = 8.53 +/- 0.13 +/- 0.22%. The ratios are found to be B (D0 → pi- e+nu)/ B (D0 → K -e+nu) = 0.084 +/- 0.003 +/- 0.001, B (D+ → pi0 e+nu)/ B (D+ → K¯0 e+nu) = 0.044 +/- 0.003 +/- 0.001, Gamma( D0 → pi-e +nu)/Gamma(D+ → pi 0e+nu) = 2.04 +/- 0.14 +/- 0.08 and Gamma(D0 → K -e+nu)/Gamma(D + → K0e +nu) = 1.06 +/- 0.02 +/- 0.03. In addition, form factors are studied through fits to the partial branching fractions obtained in five q2 ranges. Combining our results with recent unquenched lattice calculations we extract the CKM matrix elements |Vcs | and |Vcd|. Averaging over isospin conjugate modes, we find |Vcs| = 1.01 +/- 0.01 +/- 0.01 +/- 0.11 and |Vcd| = 0.217 +/- 0.010 +/- 0.004 +/- 0.023.

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.

Available in PDF, EPUB and Kindle. Book excerpt: It has recently been shown that hadrons containing a single heavy quark exhibit a new flavor-spin symmetry of QCD. We exploit this symmetry to obtain model independent predictions for the fourteen form factors in weak decays from the ground state pseudoscalar meson P(sub)Q(sub)i of a heavy quark Q(sub)i to the low-lying positive parity excited states of a heavy quark Q(sub)j in terms of two universal functions of momentum transfer. These predictions are of interest in the study of B -> D*(sub)2(2460), D(sub)1(~2460), D(sub)1(2420), and D*(sub)0(~2420) semileptonic decays. We also discuss the connection between these results and the slope of the function Xi (which determines the B->D and B->D* transition form factors) given by a heavy quark sum rule suggested by Bjorken.

Book excerpt: We present our results for the meson form factors of several semi- leptonic decays. They are computed from the corresponding matrix elements evaluated on the lattice as ratios of Greens functions. The renormalization of the local operators is calculated nonperturbatively. The dependence of the form factors on the four momentum transfer q2 is studied by injecting external three momenta to the initial and final state mesons. We study the pseudoscalar decays K → [pi]l[nu], D → Kl[nu], D → [pi]l[nu], D{sub s} → [eta]l[nu] and D{sub s} → Kl[nu] on different lattices. We also analyze scaling, finite size and SU(3) symmetry breaking effects. The uncertainties in some lattice parameters, e.g. a−1, as a source of systematic errors in this calculation are discussed. 35 refs., 15 figs., 13 tabs.
