AbstractBased on a chiral unitary approach (ChUA), S wave K pi scattering is studied. We consider K pi and K eta coupled channels on isospin bases. With only one parameter, the S wave K pi scattering phase shift data below 1.2GeV can be described, and the resultant S wave scattering lengths also coincide with the experimental values well. In this approach, a scalar resonance corresponding to the K can be generated dynamically. Its mass and width are about 725MeV and 594MeV, respectively. A resonance corresponding to the scalar K-0(*)(1430) can also be generated qualitatively.
