We have studied the Cabibbo-suppressed decay mode D0 → K+K−π0 using a Dalitz plot technique and find the strong phase difference δD ≡ δK∗−K+ − δK∗+K− = 332◦ ± 8◦ ± 11◦ and relative amplitude rD ≡ aK∗−K+ / aK∗+K− = 0.52 ± 0.05 ± 0.04. This measurement indicates significant destructive interference between D0 → K+(K−π0)K∗− and D0 → K−(K+π0)K∗+ in the Dalitz(More)
Using data collected with the CLEO detector operating at the CESR e+e− collider at √ s = 3.974.26GeV, we investigate 15 charmonium decay modes of the ψ(4040), ψ(4160), and Y (4260) resonances. We confirm, at 11σ significance, the BaBar Y (4260)→ π+π−J/ψ discovery, make the first observation of Y (4260) → π0π0J/ψ (5.1σ), and find the first evidence for Y(More)

The tracking of radiation contamination and distribution has become a high priority in the nuclear cycle industry in order to respect the ALARA principle which is a main challenge during decontamination and dismantling activities. To support this need, AREVA/CANBERRA and CEA LIST have been actively carrying out research and development on a gamma-radiation(More)
Using 281 pb−1 of e+e− collisions recorded at the ψ(3770) resonance with the CLEO-c detector at CESR, we determine absolute hadronic branching fractions of charged and neutral D mesons using a double tag technique. Among measurements for three D0 and six D+ modes, we obtain reference branching fractions B(D0 → K−π+) = (3.891 ± 0.035 ± 0.059 ± 0.035)% and(More)

We extract a relatively precise value for the decay constant of the D+ meson by measuring B(D+ → μνμ) = (4.45± 0.67 −0.36)× 10−4 using 280 pb−1 of data taken on the ψ(3770) resonance with the CLEO-c detector. We find fD+ = (223±16+7 −9) MeV . We also set a 90% confidence upper limit on B(D+ → e+ν) < 2.4× 10−5. ∗Submitted to the XXII International Symposium(More)
We have studied the inclusive photon spectra in Upsilon(2S) and Upsilon(3S) decays using a large statistics data sample obtained with the CLEO III detector. We present the most precise measurements of electric dipole (E1) photon transition rates and photon energies for Upsilon(2S) --> gammachi(bJ)(1P) and Upsilon(3S) --> gammachi(bJ)(2P) (J = 0, 1, 2). We(More)
We describe new measurements of the inclusive and exclusive branching fractions for psi(2S) transitions to J/psi using e(+)e(-) collision data collected with the CLEO detector operating at CESR. All branching fractions and ratios of branching fractions reported here represent either the most precise measurements to date or the first direct measurements.(More)
