Available in PDF, EPUB and Kindle. Book excerpt: A dedicated search for the decays K/sub L/° → [mu]e, K/sub L/° → ee and K/sub L/° → [mu][mu], was carried out at the Brookhaven National Laboratory AGS (E780). The data obtained were also used in a search for the three-body decays K/sub L/° → [pi]°l /sup /plus/1/sup -/. The two body modes were normalized to the kinelatically similar, CP violating, decay K/sub L/° → [pi]/sup (plus//[pi]/sup -/; whereas the three body modes were normalized to the decay K/sub L/° /yields/ [pi]°/pi//sup /plus//pi//sup /minus//. The search was performed on a sample of K° mesons produced in the forward direction by the interactions of 29 GeV protons on a copper target, and decaying in a 3 meter long region, starting augmented by a hydrogen Cerenkov counter and a lead glass electromagnetic calorimeter, for electron identification, and by a range stack, for muon identification. 9 refs., 5 figs., 2 tabs.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The observation that flavor-changing neutral currents (FCNC) in weak decays are highly suppressed was first explained by Glashow, Iliopoulos and Maiani in 1970, and their idea has since become a cornerstone of the Standard Model. They proposed a model of the weak interaction that included a then new fourth quark and which, in a natural way, allowed the existence of a neutral vector boson without inducing FCNC's at tree level. Thus the couplings of the neutral intermediary{hor ellipsis}cause no embarrassment.'' In higher order through, decays like K →?l{bar l} can proceed. Measurements of such processes provide a detailed test of the Standard Model since definite predictions for their rates can be calculated. Conversely, if no contradictions are found and the standard model is assumed to describe the physics, measurements limit the allowed values of the parameters of the model. As is often the case in studying processes that are highly suppressed and heretofore unseen, improvements in the sensitivity of experiments allow the possibility for the discovery of new physics that exhibits a similar experimental signature. This paper describes experiment 787 at Brookhaven which is expected to address some of these issues. The status and future of the experiment will be described here. The main goal of E787 is to measure the rate of K →?+?{bar {nu}} at the standard model level. In addition, the experiment has sensitivity to other FCNC decays of the charged kaon, in particular the decays K+ →?+?+?− and K+ →?+??

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 1997 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a search for three rare/forbidden neutral charm decays, D° → [mu]e, D° → [mu][mu], and D° → 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.

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° →?+?−)
