Model-independent resonance parameter extraction from the trace of K and T matrices
نویسندگان
چکیده
A model-independent method for the determination of resonance parameters as K-matrix pole parameters from a T matrix is presented. The method is based on eliminating the dependence on the choice of channel basis by analyzing the trace of the K and T matrices in the coupledchannel formalism, rather than individual matrix elements of the multichannel scattering matrix. © 2007 Elsevier B.V.
