Description

We have made measurements of several Ds branching ratios, relative to the φπ+ mode. We have observed two previously unseen two-body hadronic decays of the Ds+, 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 scrB(Ds→φπ+), we can account for ∼(79±26)% of all Ds+ 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
