Download or read book Search for Rare Charm Meson Decays at FNAL E791 written by and published by . This book was released on 2003 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report the results of a blind search for flavor-changing neutral current (FCNC), lepton-flavor violating, and lepton-number violating decays of D, D{sub s}, and D° mesons (and their antiparticles) into 2-, 3-, and 4-body states including a lepton pair. Such decays may involve Flavor-Changing Neutral Currents, Leptoquarks, Horizontal Gauge Bosons, or Majorana Neutrinos. No evidence for any of these decays is found. Therefore, we present 90% confidence level branching-fraction upper limits, typically at the 10−4 level. A total of 51 decay channels have been examined; 26 have not been previously reported and 18 are significant improvements over previous results.

Available in PDF, EPUB and Kindle. Book excerpt: The authors report the results of a blind search for flavor-changing neutral current, lepton-flavor violating, and lepton-number violating decays of D, D{sub s}, and D° mesons (and their antiparticles) into modes containing muons and electrons. Using data from Fermilab charm hadroproduction experiment E791, they examine the [pi]ll and Kll decay modes of D+ and D{sub s}+ and the l+l− decay modes of D°. No evidence for any of these decays is found. Therefore, they present branching-fraction upper limits at 90% confidence level for the 24 decay modes examined. Eight of these modes have no previously reported limits, and fourteen are reported with significant improvements over previously published results.

Book excerpt: Limits at the 10−4 level are reported for rare and forbidden decays of the D° charm meson to a pair of leptons and either a vector meson or two pseudoscalar mesons. Of these searches, 18 are investigations of decays without previous published results; several others have significantly improved sensitivity over previous results.

Book excerpt: I report the results of a search for flavor-changing neutral current, leptonflavor, and lepton-number violating decays of the 3 and 4-body decay modes of the D0 (and its antiparticle) containing muons and electrons. Using data from Fermilab charm hadroproduction experiment E791, I examine modes with two leptons and either a [rho]0, $\bar{K}$0, or [Phi] vector meson or a non-resonant [pi][pi], K[pi], or KK pair of pseudoscalar mesons. No evidence for any of these decays is found. Therefore, branching-fraction upper limits, typically at the 10-4 level, are presented at the 90% confidence level for the 27 decay modes examined. Of these searches, 18 are investigations of decays without previous published results; several others have significantly improved sensitivity over previous results.

Book excerpt: The authors summarize the results of two recent searches for flavor-changing neutral current, lepton-flavor violating, and lepton-number violating decays of D[sup+], D[sub s][sup+], and D[sup 0] mesons (and their antiparticles) into modes containing muons and electrons. using data from Fermilab charm hadroproduction experiment E791, they examined D[sup+] and D[sub s][sup+][pi][ell][ell] and[Kappa][ell][ell] decay modes and the D[sup 0] dilepton decay modes containing either[ell][sup+][ell][sup[minus]], a[rho][sup 0], [bar[Kappa]]*[sup 0], or[phi] vector meson, or a non-resonant[pi][pi], [Kappa][pi], or[Kappa][Kappa] pair of pseudoscalar mesons. No evidence for any of these decays was found. Therefore, the authors presented branching-fraction upper limits at 90% confidence level for the 51 decay modes examined. Twenty-six of these modes had no previously reported limits, and eighteen of the remainder were reported with significant improvements over previously published results.
