Abstract: We report the first measurement of the radium ion's $7p$ ${}^{2}P_{3/2}^o$ state branching fractions and improved theoretical calculations. With a single laser-cooled radium-226 ion we measure the $P_{3/2}$ branching fractions to the $7s$ ${}^{2}S_{1/2}$ ground…

Abstract: The present paper reports on a merged-beam experiment on mutual neutralization between ${\mathrm{Na}}^{+}$ and ${\mathrm{D}}^{\ensuremath{-}}$. For this experiment, we have used the DESIREE ion-beams storage-ring facility. The reaction products are detected using a position- and…

Abstract: We present the first measurements of the absolute branching fractions of $\Xi_c^+$ decays into $\Xi^- \pi^+ \pi^+$, $p K^- \pi^+$, and $p \bar{K}^{*}(892)^{0}$ final states. Our analysis is based on a data set of $(772\pm…

Abstract: Using the data sample of 711 fb-1 of ϒ(4S) on-resonance data taken by the Belle detector at the KEKB asymmetric-energy electron-positron collider, we present the first measurements of branching fractions of the decays B-→Λ¯c-Ξc′0, B-→Λ¯c-Ξc(2645)0, and…

Abstract: We analyze the quasi-two-body decays B+→π+ρ(770,1450)0→π+K+K- in the perturbative QCD approach. The results in this work do not support that large branching fractions contributed by the resonances ρ(770,1450)0 in the B±→π±K+K- decays. The virtual contribution…
