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. 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 +] --> [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]

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 {-+}}.

Book excerpt: We present an analysis of the decay D[sup 0] [yields] K[sup +][pi][sup -] from FOCUS. From a sample of 234 events we find a branching ratio of [Lambda](D[sup 0] [yields] K[sup +][pi][sup -])/[Lambda](D[sup 0] [yields] K[sup -][pi][sup +]) = (0.430[sub -0.061][sup +0.062] [+-] 0.031)% under the assumption of no mixing and no CP violation. We also present limits on charm mixing.

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}
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}

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains many excellent articles presenting the most recent progress in high energy physics and the current interesting problems concerning flavor physics. The reader will see how flavor physics has become a central area of particle physics, with the Standard Model (SM) being subjected to increasingly precise experiments, and why the remaining puzzles in the SM, such as the mechanisms of symmetry breaking and CP violation, as well as fermion mass and mixing generation, all are mysteries hidden in the physics of flavor. The book also shows that flavor physics is likely to be a window for probing new physics beyond the SM for many years to come.
