Every adult acute nonlymphocytic leukemia patient in Rochester, New York seen from January 1975 to January 1982 was studied. Fifty percent of the patients did not receive combination chemotherapy. Among those who did, there was a significant selection bias toward placing patients with better prognostic features on protocol. Protocol patients were also(More)
We search for the decay B ? ! ? in a sample of over 2 million charged B decays using the CLEO detector. We use the channel in which the tau decays leptonically, and combine this lepton with the missing energy and momentum in the event to form a B candidate. A t to the mass and energy distribution of these B candidates yields ?14 46 signal events. This value(More)

Four data sets collected with the MARK II detector during its operation at the SPEAR and PEP e+e-storage rings are used to study the Bose-Einstein correlation between pairs and triplets of like sign charged pions. The data sets represent four different regions of energy available for hadron production: the .7/lc, at ,/Z = 3.095 GeV, typical hadronic energy(More)
We have used the CLEO-II detector at the Cornell Electron Storage Ring to study the inclusive production of charmonium mesons in a sample of 2.15 million BB events. We nd inclusive branching fractions of (1.130.040.06)% for B!J==X, (0.340.040.03)% for B! 0 X, and (0.400.060.04)% for B! c1 X. We also nd some evidence for the inclusive production of c2. An(More)
We evaluate pseudoscalar, vector, spin 1/2 and spin 3/2 baryon masses predicted by lattice QCD with Wilson quarks in the valence (quenched) approximation for a range of different values of lattice spacing, lattice volume and quark mass. Extrapolating these results to physical quark mass, then to zero lattice spacing and infinite volume we obtain values for(More)
