[Theory-seminars] Theory Seminar on Wednesday March 6

[Alexei Prokudin]

Dear all,

we have a Theory Center Seminar on Wednesday 6th of March
CEBAF Center, Room L104
2:00 p.m.

Speaker: Michael Doering (University of Bonn)

Title: Excited hadrons from data

Abstract:  Mapping out the spectrum of excited hadrons from data is a 
cornerstone to the understanding of the strong interaction. With the 
advent of high-precision photo and electroproduction data from JLab and 
other facilities, and the future data from GlueX, there is finally the 
chance to come to more conclusive answers regarding the resonance content.
     One challenge on this path is to combine the data of different 
reactions in a global analysis while respecting unitarity, analyticity, 
gauge invariance and other theoretical requirements such as chiral 
constraints. I will present recent results of the analysis of photon and 
pion-induced reactions that allow for the reliable extraction of 
resonance poles and residues.
     Special emphasis will be placed on future challenges in the 
analysis of excited mesons and the interconnections to baryon analysis. 
Universal principles like coupled-channel unitarity even apply to the 
analysis of upcoming data of resonances decaying in the finite volume of 
lattice simulations.
