Improved Measurement of Branching Fractions for pipi Transitions among Upsilon(nS)States

CLEO Collaboration, S. R. Bhari

Using samples of (5.93 +/- 0.10) x 10^6 Upsilon(3S) decays and (9.11 +/- 0.14) x 10^6 Upsilon(2S) decays collected with the CLEO detector, we report improved measurements of the br…

Precision Measurement of B(D+ -> mu+ nu) and the Pseudoscalar Decay Constant fD+

CLEO Collaboration, B. I. Eisenstein

We measure the branching ratio of the purely leptonic decay of the D+ meson with unprecedented precision as B(D+ -> mu+ nu) = (3.82 +/- 0.32 +/- 0.09)x10^(-4), using 818/pb of data…

Search for Light CP-odd Higgs in Radiative Decays of Upsilon(1S)

CLEO Collaboration, W. Love

We search for a non-SM-like CP-odd Higgs boson (a0_1) with m(a0_1)< 2m(b) in radiative decays of the Upsilon(1S), using 21.5M Upsilon(1S) mesons directly produced in e+e- annihilat…

First Observation of Exclusive chi_cJ Decays to Two Charged and Two Neutral Hadrons

Q. He

We study exclusive chi_c0, chi_c1 and chi_c2 decays to four-hadron final states involving two charged and two neutral mesons: pi^+pi^-pi^0pi^0, K^+K^-pi^0pi^0, pppi^0pi^0, K^+K^-et…

Inclusive Radiative Decays

The CLEO Collaboration

Using data taken with the CLEO-c detector at the Cornell Electron Storage Ring, we have investigated the direct photon momentum spectrum in the decay J/psi->gamma+gluon+gluon, via…

Precision Measurement of the Mass of the h_c(1P1) State of Charmonium

CLEO Collaboration, S. Dobbs

A precision measurement of the mass of the h_c(1P1) state of charmonium has been made using a sample of 24.5 million psi(2S) events produced in e+e- annihilation at CESR. The react…
