Abstract:

Using data taken with the CLEO II detector at the Cornell Electron Storage Ring, we present the first full angular analysis in the color-suppressed modes B0→J/ψK*0 and B+→J/ψK*+. This leads to a complete determination of the decay amplitudes of these modes including the longitudinal polarization γL/γ=0.52±0.07±0.04 and the P wave component |P|2=0.16±0.08±0.04. In addition, we update the branching fractions for B→J/ψK and B→J/ψK*. © 1997 The American Physical Society.

Abstract:

Using data taken with the CLEO II detector at the Cornell Electron Storage Ring, we have determined the ratio of branching fractions: [Formula presented]. From this ratio, we have determined the QCD scale parameter [Formula presented] (defined in the modified minimal subtraction scheme) to be [Formula presented] MeV, from which we determine a value for the strong coupling constant [Formula presented], or [Formula presented]. © 1997 The American Physical Society.

Abstract:

We have searched for the rare decay of the [Formula presented] meson [Formula presented] using the CLEO II detector. The [Formula presented]’s were produced in [Formula presented] collisions with 10 GeV center-of-mass energy at the Cornell Electron Storage Ring (CESR). We find with [Formula presented] confidence the upper limit on the branching fraction [Formula presented]. The application of conventional elementary particle theory to this decay predicts a branching fraction of about [Formula presented]. © 1997 The American Physical Society.

Abstract:

Using e+e- annihilation data collected by the CLEO II detector at CESR we have observed the decay D+s→ωΠ. This final state may be produced through the annihilation decay of the D+s or through final state interactions. We find a branching ratio of γD+s→ωΠ/D+s→ηΠ=0.16α0.04±0.03 where the first error is statistical and the second is systematic. © 1998 The American Physical Society.

Abstract:

A search for the lepton-family-number-violating decays [Formula presented] and [Formula presented] has been performed using CLEO II data. No evidence of a signal has been found and the corresponding upper limits are [Formula presented] and [Formula presented] at 90% C.L. © 1997 The American Physical Society.
