Abstract
We have made measurements of several D(s) branching ratios, relative to the φπ^+ mode. We have observed two previously unseen two-body hadronic decays of the D(s)^+, namely ηρ^+ and η′ρ^+, and measured relative branching ratios of 2.86±0.38−0.38^+0.36 and 3.44±0.62−0.46^+0.44, respectively. We have determined the relative branching ratio for the decay into φρ+ to be 1.86±0.26−0.40^+0.29. In addition, we have measured relative branching ratios for the ηπ^+ and η′π^+ states, for which there had previously been conflicting measurements; our results are 0.54±0.09±0.06 and 1.20±0.15±0.11, respectively. Combining these new measurements with previous results and using (3.7±1.2)% for the value of B(D(s)→φπ^+), we can account for ≅(79±26)% of all D(s)^+ decays. In addition we have also measured relative branching ratios or set upper limits on D^+ decays to all of the above-mentioned final states.
