Update of the measurement of the cross section for e^+e^- -> psi(3770) -> hadrons

D. Besson

We have updated our measurement of the cross section for e^+e^- -> psi(3770) -> hadrons, our publication "Measurement of sigma(e^+e^- -> psi(3770) -> hadrons) at E_{c.m.} = 3773 Me…

Study of Di-Pion Transitions Among Upsilon(3S), Upsilon(2S), and Upsilon(1S) States

CLEO Collaboration, D. Cronin-Hennessy

We present measurements of decay matrix elements for hadronic transitions of the form Upsilon(nS) -> pi pi Upsilon(mS) where (n, m) = (3, 1), (2, 1), and (3, 2). We reconstruct cha…

A Search for B+ -> tau+ nu

The BABAR Collaboration, B. Aubert

We present a search for the decay B+ -> tau+ nu using 383x10^6 BBbar pairs collected at the Y(4S) resonance with the BABAR detector at the SLAC PEP-II B-Factory. A sample of events…

Measurement of Upper Limits for Upsilon --> gamma + R Decays

J. L Rosner, CLEO Collaboration

Motivated by concerns regarding possible two-body contributions to the recently-measured inclusive Upsilon(nS)->gamma+X (n=1, 2, 3) direct photon spectra, we report on a new study…

Dalitz Plot Analysis of the D+ --> pi- pi+ pi+ Decay

G. Bonvicini, CLEO Collaboration

Using 281 pb^{-1} of data recorded by the CLEO-c detector in e^+e^- collisions at the psi(3770), corresponding to 0.78 million D^+D^- pairs, we investigate the substructure of the…

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…
