| Abstract | K pi S wave scattering is studied using a chiral unitary approach (ChUT) taking into account coupled channels. With the amplitudes derived from the lowest order chiral Lagrangian as the kernel of a set of coupled channel Bathe-Salpeter equations, the I = 1/2 S wave K pi scattering phase shifts below 1.2 GeV can be fitted by one parameter, a subtraction constant, and a scalar resonance corresponding to the controversial K (K-0(*) (800)) can be generated dynamically. A good description of the I = 3/2 S wave K pi scattering phase 0 shifts below 1.2 GeV can also be obtained. An artificial singularity in the cut-off method of the 2-meson loop integral of the ChUT is found. The formalism is applied to deal with the S wave K pi final state interaction (FSI) in the decay J/psi ->(K) over bar (*0)(892)K+pi(-), and a qualitatively good fit to the data is achieved. The role Of K in the decay is discussed. (c) 2006 Elsevier B.V. All rights reserved. |
