Abstract

We measure the inclusive branching fractions of charm mesons into three mesons with large ss̄ content, namely, the η, η′ and. Data were accumulated with the CLEO-c detector. For D0 and D+ rates, we use 281pb-1 taken on the ψ(3770) resonance, and for Ds+ rates, we use 195pb-1 taken at 4170 MeV. We find that the production rates of these particles are larger in Ds+ decays than in D0 and D+ decays. The rate, in particular, is 15 times greater. These branching fractions can be used to measure Bs yields either at the Υ(5S) resonance or at hadron colliders. © 2006 The American Physical Society.
