AB - We study the meson-baryon interaction in S-wave in the strangeness S=-1 sector using a chiral SU(3) Lagrangian extended to next-to-leading order (NLO). Our model has 7 new parameters, coming from NLO terms in the chiral Lagrangian, which are fitted to the large set of experimental data available for different two-body channels. We pay particular attention to the K<sup>−</sup> p → K Ξ reactions, where the effect of the NLO terms in the Lagrangian is very important. In order to improve our model in these particular channels, we take into account phenomenologically the effects of the high spin hyperonic resonances, namely Σ(2030) ( \frac72<sup>+</sup> ) and Σ(2250) ( \frac52<sup>−</sup> ). Finally, the developed model is applied to simulate the Ξ production in nuclei.
