Available in PDF, EPUB and Kindle. Book excerpt: Based on an 87-fb[sup -1] dataset collected by the BABAR detector at the PEP-II asymmetric-energy B-Factory, a search for D[sup 0]-[bar D][sup 0] mixing has been made using the semileptonic decay modes D*[sup +] --> [pi][sup +] D[sup 0][sub z] D[sup 0] --> K*[epsilon][nu] (+c.c.). The use of these modes allows unambiguous flavor tagging and a combined fit of the D[sup 0] decay time and D*[sup +]-D[sup 0] mass difference ([Delta]M) distributions. The high-statistics sample of unmixed semileptonic D[sup 0] decays is used to model the [Delta]M distribution and time-dependence of mixed events directly from the data. Neural networks are used to select events and reconstruct the D[sup 0]. A result consistent with no charm mixing has been obtained. R[sub mix] = 0.0023 [+-] 0.0012 [+-] 0.0004. This corresponds to an upper limit of R[sub mix]

Available in PDF, EPUB and Kindle. Book excerpt: Based on an 87-fb−1 dataset collected by the BABAR detector at the PEP-II asymmetric-energy B-Factory, a search for D°-{bar D}° mixing has been made using the semileptonic decay modes D* -->?+ D°{sub z} D° --> K*?? (+c.c.). The use of these modes allows unambiguous flavor tagging and a combined fit of the D° decay time and D*+-D° mass difference (?M) distributions. The high-statistics sample of unmixed semileptonic D° decays is used to model the?M distribution and time-dependence of mixed events directly from the data. Neural networks are used to select events and reconstruct the D°. A result consistent with no charm mixing has been obtained. R{sub mix} = 0.0023 ± 0.0012 ± 0.0004. This corresponds to an upper limit of R{sub mix}

Available in PDF, EPUB and Kindle. Book excerpt: Based on an 87-fb{sup -1} dataset collected by the Babar detector at the PEP-II asymmetric-energy B-Factory, a search for D{sup 0}-{bar D}{sup 0} mixing has been made using the semileptonic decay modes D*{sup +} {yields} {pi}{sup +}D{sup 0}, D{sup 0} {yields} Ke{nu} (+c.c.). The use of these modes allows unambiguous flavor tagging and a combined fit of the D{sup 0} decay time and D*{sup +}-D{sup 0} mass difference ({Delta}M) distributions. The high-statistics sample of unmixed semileptonic D{sup 0} decays is used to model the {Delta}M distribution and time-dependence of mixed events directly from the data. Neural networks are used to select events and reconstruct the D{sup 0}. A result consistent with no charm mixing has been obtained, R{sub mix} = 0.0023 {+-} 0.0012 {+-} 0.0004.

Book Synopsis Search for Neutral D Meson Mixing Using Semileptonic Decays by : Kevin T. Flood
Download or read book Search for Neutral D Meson Mixing Using Semileptonic Decays written by Kevin T. Flood and published by . This book was released on 2006 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a 87 fb{sup -1} dataset, a search for D{sup 0}-{bar D}{sup 0} mixing is made using the semileptonic decay modes D*{sup +} {yields} {pi}{sup +} D{sup 0}, D{sup 0} {yields} [K/K*]e{nu} (+c.c.) at the B-Factory facility at the Stanford Linear Accelerator Center. These modes offer unambiguous initial and final-state charm flavor tags, and allow the combined use of the D{sup 0} lifetime and D*{sup +}-D{sup 0} mass difference ({Delta}M) in a global likelihood fit. The high-statistics sample of reconstructed unmixed semileptonic D{sup 0} decays is used to model both the {Delta}M distribution and the time-dependence of mixed events directly from the data. Neural networks are used both to select events and to fully reconstruct the D{sup 0}. A result consistent with no charm mixing has been obtained, R{sub mix}
Book Synopsis Search for D0 - D0bar Mixing and Rare Charm Decays by : U. Egede
Download or read book Search for D0 - D0bar Mixing and Rare Charm Decays written by U. Egede and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a dataset acquired by the BABAR experiment running on and near the {Upsilon}(4S) resonance from 1999-2002, an upper limit is set on the rate of D{sup 0}-{bar D}{sup 0} mixing using the decay mode D*{sup +} {yields} D{sup 0}{pi}{sup +}, followed by a semi-leptonic decay of the D{sup 0}. Results are compared to previous BABAR analysis using hadronic decays. We also set limits on the flavor-changing neutral current decays D{sup 0} {yields} e{sup +}e{sup -} ({mu}{sup +}{mu}{sup -}) and the lepton-flavor violation decays D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}.
