We have constructed eﬀective separable meson-baryon potentials to match the equivalent chiral amplitudes up to the second order in external meson momenta. The parameters of the model were ﬁtted to the threshold and low energy K−p data including the 1s level characteristics of the kaonic hydrogen atom. We discuss the results of our ﬁts and use the model to calculate the πΣ mass spectrum and the energy dependence of the K−N amplitudes.
