Abstract//


After the development of QCD in the last quarter of the 20th century, we 
are now in the early years of an exciting new era in which much more 
quantitative QCD calculations can be tested against increasingly 
sophisticated experimental measurements.  Advances include a greater 
focus on the *dynamics* of quarks and gluons within bound states and in 
the process of bound-state formation.  Over the last decade and a half, 
studies initially focused on spin-momentum correlations in the proton 
have brought to the fore several deep, fundamental issues within QCD. 
  We are now exploring the physical consequences of gauge invariance in 
QCD as a quantum field theory, analogous to the Aharonov-Bohm effects 
familiar to many from QED but predicted for any gauge-invariant quantum 
field theory.  Given the unique non-Abelian nature of the QCD gauge 
group, these quantum mechanical phase effects lead to an exciting novel 
prediction of entanglement of quarks and gluons *across* QCD bound states.
