Abstract
In the present work, we use the final state interaction formalism to investigate the production of the $f_0(1710) $ and $a_0(1710) $ states in the $D_s$ decay processes.
At the quark level, we consider the W-internal and -external emission mechanisms.
At the hadron level, we take the final state interaction into account based on the coupled channel approach, where the $f_0(1710) $ and $a_0(1710) $ states are dynamically generated as the molecular states of $K^*\bar{K}^*$.
The experimental data of the invariant mass spectra is fitted well, and some corresponded branching fractions are evaluated, which are consistent with the experimental measurements.
