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…
Radiative Decays of the Upsilon(1S) to gamma pi^0 pi^0, and gamma eta eta and gamma pi^0 eta
D. Besson, CLEO Collaboration
We report on a study of exclusive radiative decays of the Upsilon(1S) resonance into the final states gamma pi^0 pi^0, gamma eta eta and gamma pi^0 eta, using 1.13 inverse femto-ba…
Experimental Study of chi_b(2P) --> pi pi chi_b(1P)
C. Cawlfield, CLEO Collaboration
We have searched for the di-pion transition chi_b(2P) -> pi pi chi_b(1P) in the CLEO III sample of Upsilon(3S) decays in the exclusive decay chain: Upsilon(3S) -> gamma chi_b(2P),…
Dark Matter in Many Forms
Jonathan L. Rosner
Since ordinary matter constitutes about 4% of the closure density of the Universe while dark matter constitutes about six times as much, it is urged that searches for dark matter c…
Radiative Decays of the Upsilon(1S) to a Pair of Charged Hadrons
S. B. Athar, CLEO Collaboration
Using data obtained with the CLEO~III detector, running at the Cornell Electron Storage Ring (CESR), we report on a new study of exclusive radiative Upsilon(1S) decays into the fin…

Present and future contributions of the CLEO experiment to the study of Dalitz plots are presented. Such Dalitz plots can be of help in determining weak phases from …
Symmetry relations in charmless B->PPP decays
Michael Gronau, Jonathan L. Rosner
Strangeness-changing decays of mesons to three-body final states of pions and kaons are studied, assuming that they are dominated by a penguin amplitude with flavor stru…
