Generalized Parton Distributions

( ) ( ) ( ) ( )txEtxEtxHtxH ~~ ξξξξFor the unpolarized or longitudinal polarized case there are 4 GPDs

After Fourier transformlongitudinal momentum distributions of quark at a given transverse point in the nucleon

rArr 3D imaging of the nucleon

GPDs are not directly accessiblerArr - need deconvolution

- model dependent

GPDs are the generalization of partondistribution functions when one allows- momentum transfer to the nucleon- longitudinal momentum transfer to the quark

DIS cross section

They represent interference of amplitudes rArr NO probabilistic interpretation

GPDs from theory to experiments

Can be measured in exclusive electroproductionexperiments

Deeply Virtual Compton Scattering (DVCS)

Meson Spectroscopy with real photonsMeson (and baryon) spectroscopy with real photons is the main goal of the Hall-D- exotic JPC more likely produced by J=1 probe- production rate comparable to regular mesons

This program can be pursued in a complementary way in Hall-B- high luminosity- ldquotaggingrdquo of the photon - linear polarization to simplify Partial Wave Analysis
