Abstract:

In this paper, we review our recent series of works where we determine the parameters of light strange resonances using data on K ! K and ! K K and model-independent dispersive methods or techniques based on complex analysis. We also advance some preliminary results on a modelindependent determination of the or K 0 (700) resonance parameters.
