Poles and resonances in the coupled channels model for anti-K N > interaction
Original language description
We study dynamically generated resonances that arise as a result of low energy meson-baryon interaction in a chirally motivated coupled channel model. Our approach is based on a solution of the Lippman?Schwinger equation for the coupled meson-baryon channels ??, ??, KN , ??, ??, and K? with an interaction kernel taken in a separable form. The resonances are searched for as poles of the T-matrix on unphysical Riemann sheets in the complex energy plane. We examine s-wave resonances with strangeness S = 1with accent on isoscalar resonances ?(1405) and ?(1670). Additional insights are obtained by investigating movement of the poles to the zero coupling limit and to the SU(3) symmetry restoraton limit.
