Abstract:

Using a sample of 25.9×106 ψ(2S) decays acquired with the CLEO-c detector at the CESR e+e- collider, we report branching fractions for the decays χcJ→pp̄π0, pp̄η, and pp̄ω, with J=0, 1, 2. Our results for B(χcJ→pp̄π0) and B(χcJ→pp̄η) are consistent with, but more precise than, previous measurements. Furthermore, we include the first measurement of B(χcJ→pp̄ω). © 2010 The American Physical Society.

Analysis of D⁺→K^-π⁺e ⁺νe and D⁺→K ^-π⁺μ⁺+νμ semileptonic decays

Abstract:

Using a large sample (≈11800 events) of D+→K -π+e+νe and D+→K -π+μ+νμ decays collected by the CLEO-c detector running at the ψ(3770), we measure the helicity basis form factors free from the assumptions of spectroscopic pole dominance and provide new, accurate measurements of the absolute branching fractions for D +→K̄*0e+νe and D+→K̄*0μ+νμ decays. We find branching fractions which are consistent with previous world averages. Our measured helicity basis form factors are consistent with the spectroscopic pole dominance predictions for the three main helicity basis form factors describing D+→K̄*0 +ν decay. The ability to analyze D+→K -π+μ+νμ allows us to make the first nonparametric measurements of the mass-suppressed form factor. Our result is inconsistent with existing lattice QCD calculations. Finally, we measure the form factor that controls nonresonant s-wave interference with the D +→K̄*0+ν amplitude and search for evidence of possible additional nonresonant d- or f-wave interference with the K̄*0. © 2010 The American Physical Society.
