The work of JRE was supported by the DFG (SFB/TR 16, “Subnuclear Structure of Matter”) and the Swiss National Science Foundation.In this work we present a determination of the mass, width, and coupling of the resonances that appear in kaon-pion scattering below 1.8 GeV. These are: the much debated scalar ĸ- meson, nowadays known as K(_1)(*) (800), the scalar K(_1)(*) (1430), the K*(892) and K(_1)(*) (1410) vectors, the spin-two K(_1)(*) (1430) as well as the spin-three K(_1)(*) (1780). The parameters will be determined from the pole associated to each resonance by means of an analytic continuation of the Kπ scattering amplitudes obtained in a recent and precise data analysis constrained with dispersion relations, which were not well satisfied in previous analyses. This analytic continuation will be performed by means of Pade approximants, thus avoiding a particular model for the pole parameterization. We also pay particular attention to the evaluation of uncertainties.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttp://dx.doi.org/10.1140/epjc/s10052-017-4668-1https://link.springer.comopen access51-73Chiral perturbation-theoryPartial-wave analysis6 Gev-CS-WaveReaction K-P->Kπ&NEquation analysisKappa-resonanceMesonSystemDispersionFísica-Modelos matemáticosFísica matemática
