Abstract

Calculation of s-wave resonances by means of the analytical continuation in the coupling constant is a difficult problem because the position of the critical bifurcation point is unknown. Here we propose a new variant of the method of analytical continuation which avoids this problem completely. The method is applied to a model case which allows for accurate determination of the input data. It is shown that very precise resonance parameters can be obtained in this way.
