Strange resonance poles from scattering below 1.8 GeV
J. R. Peláez, A. Rodas, J. Ruiz de Elvira
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 -…
Forward dispersion relations for pion-kaon scattering and the K*0(800) resonance
A. Rodas, J. R. Peláez
We review our recent analysis of scattering data in terms of forward dispersion relations, and also present the parameters of the strange resonances. This work consists of fit…
Calculation of Regge trajectories of strange resonances and identification of the K0*(800) as a non-ordinary meson
J. R. Peláez, A. Rodas
We review how the Regge trajectory of an elastic resonance can be obtained just from its pole position and coupling, using a dispersive formalism. This allows us to deal correctly…
The pion-kaon scattering amplitude constrained with forward dispersion relations up to 1.6 GeV
J. R. Pelaez, A. Rodas
In this work we provide simple and precise parameterizations of the existing scattering data from threshold up to 1.6 GeV, which are constrained to satisfy forward dispersion…
