Book A Study of Exclusive Semileptonic D Decays to Pseudoscalar Pion and Kaon Final States with the CLEO c Detector

Download or read book A Study of Exclusive Semileptonic D Decays to Pseudoscalar Pion and Kaon Final States with the CLEO c Detector written by Nadia Erin Adam and published by . 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.

Book Analysis of the Neutral D meson Decay to a Neutral Kaon and Two Neutral Pions

Download or read book Analysis of the Neutral D meson Decay to a Neutral Kaon and Two Neutral Pions written by Norman A. Lowrey and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a Dalitz plot analysis of D0 to K0S PI0 PI0 using the CLEO-c data set of 818 inverse picobarns of positron-electron collisions accumulated at center-of-mass energy 3.77 GeV. This corresponds to about 3 million D0-anti-D0 pairs from which we select 1260 tagged candidates with a background of roughly 6%. We find that S-wave features dominate the PI0 PI0 axis of the Dalitz plot, contributing about one-third of the total decay rate, while the K*(892) is the dominant K0S PI0 contribution. Using three tag modes and correcting for quantum correlations we determine that the D0 to K0S PI0 PI0 branching ratio is 1.059% with a statistical uncertainty of 0.049% and a systematic uncertainty of 0.050%.
