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.

Abstract:

We have searched for lepton flavor violating decays of the τ lepton using final states with an electron or a muon and one or two π0 or η mesons but no neutrinos. The data used in the search were collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR) and correspond to an integrated luminosity of 4.68 fb−1. No evidence for signals was found, resulting in much improved limits on the branching fractions for the one-meson modes and the first upper limits for the two-meson modes. © 1997 The American Physical Society.

Abstract:

We have searched for the decay of the [Formula presented] lepton into seven charged particles and zero or one [Formula presented]. The data used in the search were collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR) and correspond to an integrated luminosity of 4.61 [Formula presented]. No evidence for a signal is found. Assuming all the charged particles are pions, we set an upper limit on the branching fraction [Formula presented] at the 90% confidence level. This limit represents a significant improvement over the previous limit. © 1997 The American Physical Society.
