Physical properties of resonances as the building blocks of multichannel scattering amplitudes
Saša Ceci, Marin Vukšić, Branimir Zauner
We propose a simple formula for multichannel resonant scattering with parameters related to physical resonant properties. It can be used to predict residue phase from other resonan…

Breit-Wigner phase is a fundamental property of a resonance
S. Ceci, M. Vukšić, B. Zauner
In the course of devising a simple method for extraction of the S-matrix poles from the data, an additional fundamental resonance property emerged. It is a reaction invariant quant…
