Abstract |
We calculate the correlation functions for the K <overline> 0 p ; c+E0;c0E+;c+A, and riE+ states, which in the chiral unitary approach predict an excited E*(1/2-) state at the Collaboration. Once this is done, we tackle the inverse problem of seeing how much information one can obtain from these correlation functions. With the resampling method, one can determine the scattering parameters of all the channels with relative precision, by means of the analysis in a general framework, and find a clear cusplike structure corresponding to the E*(1/2-) in the different amplitudes at the K <overline> N threshold.
