Available in PDF, EPUB and Kindle. Book excerpt: Presented here are the results of a direct search for flavor changing neutral currents via the rare process Z° → bs and a measurement of R{sub bs} = [Lambda](Z° → bs)/[Lambda](Z° → hadrons). Because the decays Z° → b{bar b} and Z° → c{bar c} contribute significant backgrounds to Z° → bs, simultaneous measurements of R{sub b} = [Lambda](Z° → b{bar b})/[Lambda](Z° → hadrons) and R{sub c} = [Lambda](Z° → c{bar c})/[Lambda](Z° → hadrons) were also made. The standard double tag technique was extended and self calibrating tags were used for s, c, and b quarks. These measurements were made possible by the unique capabilities of the SLAC Large Detector (SLD) at the Stanford Linear Accelerator Center (SLAC): The b and c tags relied upon the SLD's VXD3 307 megapixel CCD vertex detector for topological and kinematic reconstruction of the B and D decay vertices; the s tag identified K{sup {+-}} mesons using the particle identification capabilities of SLD's Cherenkov Ring Imaging Detector (CRID), and K{sub S}° mesons and [Lambda] hadrons by kinematic reconstruction of their decay vertices in SLD's 5120 channel central drift chamber (CDC) particle tracking system.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a blind search for the flavor changing neutral current decay of the top quark t → qZ in pp collisions at [special characters omitted] = 1.96TeV using a data sample corresponding to an integrated luminosity of 1.12 fb-1 collected by the Collider Detector at Fermilab (CDF), This decay is extremely rare in the standard model, and a signal at the Tevatron would be an indication of new physics. Dividing candidate events with a Z boson and four or more jets into a sample of those which have a heavy flavor jet identified by a secondary vertex algorithm and those which do not, we observe data yields consistent with background expectations. We set a 95% C.L. upper limit on the branching fraction B (t → qZ) of 11.3%, consistent with an expected upper limit of 7.8% ± 3.3%.

Download or read book Search for Flavor-Changing Neutral Current Top Quark Decays t → Hq, with H → bb̅ , in pp Collisions at √s = 8 TeV with the ATLAS Detector written by Shota Tsiskaridze and published by Springer. This book was released on 2017-08-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This PhD thesis focuses on the search for flavor-changing neutral currents in the decay of a top quark to an up-type quark (q = u, c) and the Standard Model Higgs boson, where the Higgs boson decays to bb. Further, the thesis presents the combination of this search for top quark pair events with other ATLAS searches – in the course of which the most restrictive bounds to date on tqH interactions were obtained. Following on from the discovery of the Higgs boson, it is particularly important to measure the Yukawa couplings of the Standard Model fermions; these parameters may provide crucial insights to help solve the flavor puzzle and may help reveal the presence of new physics before it is directly observed in experiments.

Available in PDF, EPUB and Kindle. Book excerpt: We report on a search for the flavor-changing neutral-current decay D° →??− in p{bar p} collisions at √s = 1.96TeV using 360 pb−1 of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron collider. A displaced vertex trigger selects long-lived D° candidates in the?+?−,?+?−, and K−?+ decay modes. We use the Cabibbo-favored D° → K−?+ channel to optimize the selection criteria in an unbiased manner, and the kinematically similar D° →?+?− channel for normalization. We set an upper limit on the branching fraction?(D° →?+?−)

This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report on a search for the flavor-changing neutral current decays D° --> ee− and D° -->?+?−, and the lepton-flavor violating decay D° --> e{sup {+-}}?{sup {-+}}. The measurement is based on 122 fb−1 of data collected by the BABAR detector at the PEP-II asymmetric e+e− collider. No evidence is found for any of the decays. The upper limits on the branching fractions, at the 90% confidence level, are 1.2 x 10−6 for D° --> e+e−, 1.3 x 10−6 for D° -->?+?−, and 8.1 x 10−7 for D° --> e{sup {+-}}?{sup {-+}}.

Book excerpt: The Tevatron, with p{bar p} collisions at (square root)s = 1.96 TeV, can produce all flavors of B hadrons and allows for unprecedented studies in the B physics sector. These range from measurements of B hadron properties to searches of new physics signatures. The CDF1 and D02 detectors currently have more than 7 fb−1 of data recorded. This paper presents a selection of recent results on lifetimes and flavor changing neutral currents using between 4.3-5.0 fb−1 of data.

Available in PDF, EPUB and Kindle. Book excerpt: Neutral current interactions are known from studies of K meson decays to conserve flavor to a high precision. Although flavor changing neutral currents (FCNC) are forbidden in the Weinberg-Salam model, many extensions of the Standard Model allow such processes. We present preliminary upper limits on FCNC-mediated decays of charmed particles, namely D° .-->. ee−, D° .-->. .mu.mu.−, D° .-->. .mu.e and D+ .-->. .pi.+.mu.e.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a search for three rare/forbidden neutral charm decays, D[sup 0][yields][mu]e, D[sup 0][yields][mu][mu], and D[sup 0][yields] ee. This study was based on data collected in Experiment E789 at the Fermi National Accelerator Laboratory using 800 GeV/c proton-gold interactions. Two statistical analyses are presented, one with background subtraction and the other without background subtraction. No evidence is found for any of the decays and the following upper limits are presented at the 90% confidence level.
