A Dalitz-plot analysis of the Cabibbo-favored decay D+ → K- π+ π+ using data from Fermilab experiment was presented. The experiment was based on the Fermilab E791 sample of 2×1010 events produced from interactions of a 500 GeV/c π- beam with five thin target foils. Results provided informations on the scalar sector in hadron spectroscopy.
