Description

Motivated by the 1/Nc expansion, we study a simple model in which the πK scattering amplitude is the sum of a current-algebra contact term and resonance pole exchange. This phenomenological model is crossing symmetric and, when a putative light strange scalar meson κ is included, satisfies the unitarity bounds to well above 1 GeV. The model also features chiral dynamics, vector meson dominance and appropriate interference between the established K0*(1430) resonance and its predicted background
