Description
We present a determination of the mass, width and coupling of the strange resonances appearing in pion-kaon scattering, the much debated K_0(800), the scalar K_0(1430), the K_1(892) and k_1(1410) vectors, the spin-two K_2(1430) as well as the spin-three K_3(1780). The parameters of each resonance will be determined using a direct analytical continuation of the pion-kaon partial waves by means of Padé approximants, thus avoiding any particular model description and taking into account the analytic requirements imposed by dispersion relations.
