Measurements of inclusive B → ψ production

Physical Review Letters 89:28 I (2002)

Authors:

Abstract:

The properties of ψ mesons produced directly from decays of the Β meson were measured. Focus was on events that have spherical energy distributions and are likely to be hadronic. The resultant data were analyzed in detail.

Abstract:

Using the combined CLEO II and CLEO II.V data sets of 9.1 fb(-1) at the Upsilon(4S), we measure properties of psi mesons produced directly from decays of the B meson, where "B" denotes an admixture of B+, B-, B0, and B;(0), and "psi" denotes either J/psi(1S) or psi(2S). We report first measurements of psi polarization in B-->psi(direct)X: alpha(psi(1S))=-0.30(+0.07)(-0.06)+/-0.04 and alpha(psi(2S))=-0.45(+0.22)(-0.19)+/-0.04. We also report improved measurements of the momentum distributions of psi produced directly from B decays, correcting for measurement smearing. Finally, we report measurements of the inclusive branching fraction for B-->psiX and B-->chi(c1)X.

Dalitz analysis of D⁰ → KS⁰π⁺π^-

Physical Review Letters 89:25 (2002)

Authors:

Abstract:

The resonant substructure of the decay D0→KS0π+π- was analyzed using the Dalitz technique. Ten contributions were observed including a wrong sign D0→K*(892)+π- amplitude with a significance of 5.5 standard deviations.

Abstract:

In e(+)e(-) collisions using the CLEO detector, we have studied the decay of the D0 to the final state K(0)(S)pi(+)pi(-) with the initial flavor of the D0 tagged by the decay D(*+)-->D0pi(+). We use the Dalitz technique to measure the resonant substructure in this final state and clearly observe ten different contributions by fitting for their amplitudes and relative phases. We observe a K(*)(892)(+)pi(-) component which arises from doubly Cabibbo suppressed decays or D0-D0; mixing.

Abstract:

The three-body decay Β→K0π+π- with a branching fraction (50-9+10±7)X10-6 was observed. A simultaneous analysis of the Dalitz plots for this decay and for Β→K+π-π0 revealed the presence of Β→K*+(892)π- with a branching fraction (16-5+6±2)X10-6, which is larger than but consistent with most theoretical predictions.
