We report 3 patients who underwent total hip arthroplasty (THA) using large diameter metal-on-metal bearing. These patients initially presented with pain but went on to develop dislocation of the THA while awaiting investigations. Any pain following metal-on-metal bearing THA should be taken seriously and should trigger investigations to identify a metal(More)
Using data collected in the region of the Υ(4S) resonance with the CLEO II detector operating at the Cornell Electron Storage Ring (CESR), we present the first observation of B mesons decaying into the charmed strange baryons Ξc and Ξ + c . We find 79 ± 27 Ξ 0 c and 125 ± 28 Ξ + c candidates from B decays, leading to product branching fractions of B(B →(More)
The decays Υ(4S) → BB, followed by B → Dπ and D → Dπ, permit reconstruction of all kinematic quantities that describe the sequence without reconstruction of the D, with reasonably low backgrounds. Using an integrated e+e− luminosity of 3.1 fb accumulated at the Υ(4S) by the CLEO-II detector, we report measurements of B(B 0 →D∗+ π) = (2.81 ± 0.11 ± 0.21 ±(More)
Using the CLEO II detector, we have measured the di erential cross sections for exclusive two-photon production of light pseudoscalar mesons 0, , and . From our measurements we have obtained the form factors associated with the electromagnetic transitions ! meson. We have measured these form factors in the momentum transfer ranges from 1.5 to 9, 20, and 30(More)
