Resonance parameters from K-matrix and T-matrix poles | R.L. Workman
; R.A. Arndt
; | Date: |
15 Aug 2008 | Abstract: | We extract K-matrix poles from our fits to elastic pion-nucleon scattering
and eta-nucleon production data in order to test a recently proposed method for
the determination of resonance properties, based on the trace of the K-matrix.
We have considered issues associated with the separation of background and
resonance contributions, the correspondence between K-matrix and T-matrix
poles, and the complicated behavior of eigenphases. | Source: | arXiv, 0808.2176 | Services: | Forum | Review | PDF | Favorites |
