Quark Hadron Duality Workshop: Probing the Transition from Free to
Confined Quarks
September 23-25, 2018
James Madison University
Harrisonburg, VA

We would like to invite you to participate in the Quark Hadron Duality
Workshop which will be held at James Madison University on September
23-25, 2018. The aim of this workshop is to revisit the puzzle of
quark-hadron duality at the dawn of the 12 GeV era at Jefferson Lab.

In the 6 GeV era, duality has been observed to hold in an unprecedented
variety of experiments and observables.  While perturbative QCD methods
accurately describe experimental results at high energies, and chiral
expansion techniques can provide effective parametrizations of low energy
data, a wide variety of reactions can be approximated by either single
particle (quark) scattering or by exclusive resonance (hadron)
interactions.  The "duality" transcending these two regimes appears to be
an intrinsic, unwavering property of nucleon structure; yet, its dynamical
origin remains an unsolved mystery.

This workshop will be a forum for experimentalists and theorists to review
our existing understanding of duality, present new results and data, and
discuss anticipated experiments and new theoretical ideas that can foster
future research.  The context of the discussion of duality will be from
the point of view of the transition from confined to free partons.
If you are interested in presenting at this workshop please contact one of
the members of the organizing committee.
