SUMMARY:Baryons: Testing Ground of QCD Dynamics\, Physics Department C
 olloquium\, Jose Goity\, JLab/Hampton University
DESCRIPTION:Quantum Chromodynamics\, QCD\, has been established as the
  fundamental theory of the strong interaction for a long time\, yet it
 s non-perturbative dynamics remains incompletely understood. Most prop
 erties of hadrons\, such as those of the familiar proton and neutron\,
  are determined by these non-perturbative dynamics\, and through the e
 xperimental and theoretical study of hadrons important aspects are bei
 ng revealed. This talk will focus on the role played by the study of b
 aryons\, discussing in particular the spectrum of excited baryons. Two
  significant theoretical advances will be highlighted: studies of the 
 baryon spectrum by means of lattice simulations of QCD\, and analysis 
 of that spectrum by the implementation of the 1/Nc expansion\, where N
 c is the number of color degrees of freedom in QCD.
