Taking into account that the scalar can be dynamically generated from the pseudoscalar-pseudoscalar interaction within the chiral unitary approach, we have studied the single Cabibbo suppressed process . We find clear peaks of and in the and invariant mass distributions, respectively. The predicted Dalitz plots of also manifest the significant signals for and states. The uncertainties of the results due to the free parameters are also discussed. Our study shows that the process can be used to explore the nature of the scalar , thus we encourage the experimental physicists to measure this reaction with more precision.
