Sažetak
A model-independent method for the determination of Breit-Wigner resonance parameters is presented. The method is based on eliminating the dependence on the choice of channel basis. It is done by analyzing the trace of K and T matrices in the coupled-channel formalism, instead of individual matrix elements of the multichannel scattering matrix.
