Mitchell R, Shepherd M, Besson D, Pedlar T, Cronin-Hennessy D, Gao K, et al.
Phys Rev Lett . 2009 Mar; 102(1):011801. PMID: 19257180
Using 2.45x10;{7} psi(2S) decays collected with the CLEO-c detector at the Cornell Electron Storage Ring we present the most precise measurements of magnetic dipole transitions in the charmonium system. We...

Love W, Savinov V, Lopez A, Mehrabyan S, Mendez H, Ramirez J, et al.
Phys Rev Lett . 2008 Dec; 101(20):201601. PMID: 19113327
In this Letter, we describe a search for lepton flavor violation (LFV) in the bottomonium system. We search for leptonic decays Upsilon(nS)-->mutau (n=1, 2, and 3) using the data collected...

He Q, Insler J, Muramatsu H, Park C, Thorndike E, Yang F, et al.
Phys Rev Lett . 2008 Dec; 101(19):192001. PMID: 19113261
We report the first observation of Upsilon(2S)-->etaUpsilon(1S), with a branching fraction B=(2.1(-0.6)+0.7(stat)+/-0.3(syst)) x 10(-4) and a statistical significance 5.3sigma. Data were acquired with the CLEO III detector at the CESR...

Dobbs S, Metreveli Z, Seth K, Tomaradze A, Libby J, Powell A, et al.
Phys Rev Lett . 2008 Nov; 101(18):182003. PMID: 18999820
A precision measurement of the mass of the h_{c}(1P1) state of charmonium has been made using a sample of 24.5x10;{6} psi(2S) events produced in e;{+}e;{-} annihilation at the Cornell Electron...

Libby J, Martin L, Powell A, Wilkinson G, Ecklund K, Love W, et al.
Phys Rev Lett . 2008 Nov; 101(18):182002. PMID: 18999819
We measure the mass of the eta;{'} meson using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector operating at the CESR e;{+}e;{-} collider. Using three decay modes, eta;{'}-->rho;{0}gamma, eta;{'}-->pi;{+}pi;{-}eta with...

Love W, Savinov V, Mendez H, Ge J, Miller D, Shipsey I, et al.
Phys Rev Lett . 2008 Nov; 101(15):151802. PMID: 18999589
We search for a non-SM-like CP-odd Higgs boson (a(1)(0)) decaying to tau(+)tau(-) or mu(+)mu(-) in radiative decays of the Upsilon(1S). No significant signal is found, and upper limits on the...

Phys Rev Lett . 2008 Nov; 101(15):151801. PMID: 18999588
Using a total of 2.74 x 10(7) decays of the psi(2S) collected with the CLEO-c detector, we present a study of chi(cJ)-->gammaV, where V=rho(0), omega, phi. The transitions chi(c1)-->gammarho(0 and...

Adams G, Anderson M, Cummings J, Danko I, Hu D, Moziak B, et al.
Phys Rev Lett . 2008 Oct; 101(10):101801. PMID: 18851203
We report the first observation of the decay J/psi-->3gamma. The signal has a statistical significance of 6sigma and corresponds to a branching fraction of B(J/psi-->3gamma)=(1.2+/-0.3+/-0.2)x10;{-5}, in which the errors are...

Cronin-Hennessy D, Gao K, Gong D, Hietala J, Kubota Y, Klein T, et al.
Phys Rev Lett . 2008 Jul; 100(25):251802. PMID: 18643653
By using 1.8x10{6} DDpairs, we have measured B(D{0}-->pi{-}e{+}nu{e})=0.299(11)(9)%, B(D{+}-->pi{0}e{+}nu{e})=0.373(22)(13)%, B(D{0}-->K{-}e{+}nu{e})=3.56(3)(9)%, and B(D{+}-->K{0}e{+}nu{e})=8.53(13)(23)% and have studied the q;{2} dependence of the form factors. By combining our results with recent lattice calculations,...

Phys Rev Lett . 2008 Jul; 100(22):221801. PMID: 18643413
We exploit the quantum coherence between pair-produced D0 and D[over]0 in psi(3770) decays to study charm mixing, which is characterized by the parameters x and y, and to make a...
