New Measurements of Cabibbo-Suppressed Decays of D Mesons in CLEO-c

P. Rubin, CLEO Collaboration

Using 281 pb^-1 of data collected with the CLEO-c detector, we report on first observations and new measurements of Cabibbo-suppressed decays of D mesons to 2, 3, 4, and 5 pions. B…

Measurement of sigma(e^+e^- --> psi(3770) --> hadrons) at E_{cm}=3773 MeV

D. Besson

We measure the cross section for e^+e^- -> ψ(3770) -> hadrons at Ecm=3773 MeV to be (6.38+-0.08^{+0.41}_{-0.30}) nb using the CLEO detector at the CESR e^+e^- collider. The differe…

Type Ia Supernova Spectral Line Ratios as Luminosity Indicators

Sebastien Bongard, E. Baron, G. Smadja +2

Type Ia supernovae have played a crucial role in the discovery of the dark energy, via the measurement of their light curves and the determination of the peak brightness via fittin…

New CP-odd Observable in H -> t \bar{t}

G. Valencia, Yili Wang

We study a CP-violating triple product correlation that occurs in the decay of a neutral Higgs boson into t\bar{t} pairs when the Higgs boson does not have a definite CP nature. We…

Measurement of the Direct Photon Momentum Spectrum in Upsilon(1S), Upsilon(2S), and Upsilon(3S) Decays

D. Besson, CLEO Collaboration

Using data taken with the CLEO III detector at the Cornell Electron Storage Ring, we have investigated the direct photon spectrum in the decays Upsilon(1S) -> gggamma, Upsilon(2S)…
