Search for rare and forbidden charm meson decays at Fermilab E791

Conference ·
OSTI ID:764140
The authors report the results of a blind search 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 examine the {pi}{ell}{ell} and K{ell}{ell} decay modes of D{sup +} and D{sub s}{sup +} and the {ell}{sup +}{ell}{sup {minus}} decay modes of D{sup 0}. 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.
