[Theory-seminars] Cake seminar on Wednesday, April 14

[vguzey at jlab.org]

Dear all,

This is a reminder that we will have a cake seminar on Wednesday, April 14
at 3 pm in room L102/L104.

Speaker: Hiroyuki Kamano (JLab)
Title:  Extracting the resonance information with a dynamical
coupled-channels model
Abstract:

A continuous effort to explore the nature of N* states has been
made in Excited Baryon Analysis Center by analyzing the world data
of meson production reactions off the nucleon target.
The analysis is pursued with a unitarized dynamical coupled-channels model,
which takes account of couplings among relevant reaction channels
in the energy region under the consideration.
Once a reaction model is constructed by analyzing the reaction data,
various information on the nucleon resonances, such as poles and decay
vertices, can be extracted from the model.
In this talk, I will explain how we make such an extraction practically and
discuss a role played by the analytic structure of the scattering amplitudes
on the complex energy plane in understanding the resonance properties.
