"Nucleon and Resonance Structure with Hard Exclusive Processes"

29 mai 2017, 08:45 → 31 mai 2017, 18:55 Europe/Paris

Auditorium Joliot Curie (IPN Orsay)

The 3-day workshop will focus on new approaches to exploring the short-range structure of baryons and non-perturbative QCD phenomena such as chiral symmetry breaking confinement using hard exclusive electromagnetic processes. Particular emphasis will be placed on a unified description of processes in the deep-exclusive regime (Generalized Parton Distributions, GPDs) and the resonance region (N* physics).

The workshop will bring together experts in perturbative QCD, phenomenology of electromagnetic processes, and dynamical models of hadron structure, to discuss the impact of present and future experiments (particularly with the JLab 12 GeV upgrade), assess the reach of present theoretical methods, identify directions for further development, and enable joint approaches to the study of GPDs and N* physics.

Topics include:

-- Status and perspectives of GPD analysis

-- Chiral-even GPDs and DVCS

-- Chiral-odd GPDs and pseudoscalar mesons

-- Gluon GPDs and vector mesons

-- Reaction models for N* production

-- QCD-based approaches to N* transition form factors

-- Transverse densities of baryon resonances

-- Dispersion relations for exclusive processes

-- Joint simulation tools for GPDs and N* physics

The workshop will include two special sessions: one session in honor of Paul Stoler’s retirement to celebrate him and his many contributions to the field of hadronic physics, and another on US-France-South Korea collaboration on hadron physics with the 12 GeV JLab upgrade and Electron Ion Collider (EIC).
