متن کاملBranching Fraction Measurements of the Decays B → η
In this report, we present the observation of the exclusive decays B → ηcK and B → ηcK, and the measurement of the related branching fractions. Using a sample of 22.7×10 Υ (4S) → BB decays collected with the BABAR detector at the SLAC PEP-II asymmetric B Factory during 19992000, we have observed statistically significant signals in the ηc → K SKπ and KKπ channels and set upper limits in the ηc ...
متن کاملThe need for branching fraction measurements in multiply-charged ions
Much progress has been made in the measurement of oscillator strengths in neutral and singly-ionized atoms, providing a database for use in important applications. However, for multiply-charged ions, measured data for oscillator strengths are almost exclusively limited to low-lying unbranched transitions. Although extensive measurements of ionic lifetimes exist, the lack of branching fraction m...
متن کاملAbsolute branching fraction measurements of exclusive D+ semileptonic decays.
Using data collected at the psi(3770) resonance with the CLEO-c detector at the Cornell e+e- storage ring, we present improved measurements of the absolute branching fractions of D+decays to K0e+ve, pi0e+ve, K*0e+ve, and p0e+ve, and the first observation and absolute branching fraction measurement of D+ --> omega e+ve. We also report the most precise tests to date of isospin invariance in semil...
