BaBar, CLEO-c and Belle collaborations have measured the absolute branching fractions of hadronic decays,
Ds+ → K-K+π+,
Ds+ → K0π+, and
Ds+ → ηπ+. The first two decay modes are the reference modes
for the measurements of branching fractions of the Ds+ decays to any other final state.
Table and figure 1 (figure 2, figure 3)
summarise the individual measurements and averaged values, which are found to be
