    "abstract": "The pi N --\u003e KY and KY --\u003e KY reactions are studied using a dynamical\ncoupled-channel model of meson-baryon interactions at energies where the baryon\nresonances are strongly excited. The channels included are: pi N, K \\Lambda,\nand K\\Sigma. The resonances considered are: N^* [S_{11}(1650), P_{11}(1710),\nP_{13}(1720),D_{13}(1700)]; \\Delta^* [S_{31}(1900), P_{31}(1910),\nP_{33}(1920)]; \\Lambda ^* [S_{01}(1670), P_{01}(1810)] \\Sigma^* [P_{11}(1660),\nD_{13}(1670)]; and K^*(892). The basic non-resonant \\pi N --\u003e KY and KY --\u003e KY\ntransition potentials are derived from effective Lagrangians using a unitary\ntransformation method. The dynamical coupled-channel equations are simplified\nby parametrizing the pi N --\u003epi N amplitudes in terms of empirical pi N\npartial-wave amplitudes and a phenomenological off-shell function. Two models\nhave been constructed. Model A is built by fixing all coupling constants and\nresonance parameters using SU(3) symmetry, the Particle Data Group values, and\nresults from a constituent quark model. Model B is obtained by allowing most of\nthe parameters to vary around the values of model A in fitting the data. Good\nfits to the available data for pi^- p to K^0 \\Lambda, K^0 \\Sigma^0 have been\nachieved. The investigated kinematics region in the center-of-mass frame goes\nfrom threshold to 2.5 GeV. The constructed models can be imbedded into\nassociated dynamical coupled-channel studies of kaon photo- and\nelectro-production reactions.",
