We propose to study theand theresonances in thedecay via the final-state interactions of theandpairs. The weak interaction part proceeds through thecquark decay process:, while the hadronization part takes place in two mechanisms, differing in how the quarks from the weak decay combines intowith awith the quantum numbers of the vacuum. Because the finalandstates are in pure isospinandcombinations, thedecay can be an ideal process to study theandresonances. Describing the final-state interaction in the chiral unitary approach, we find that theandinvariant mass distributions, up to an arbitrary normalization, show clear cusp and peak structures, which can be associated with theandresonances, respectively. The proposed mechanism can provide valuable information on the nature of these resonances and can in principle be tested by facilities such as BEPCII.
