Query: Deuteron Photodisintegration in the Quark-Hadron Picture   The study of the two-body photodisintegration of the deuteron in the few GeV
region is the ideal reaction to clarify the transition from the nucleonic
degrees of freedom to the QCD picture of hadrons. The CLAS large angle
spectrometer of Hall B at Jlab allowed for the first time the complete
measurement of the angular distribution of the differential cross section at
photon energy between 0.5 and 3 GeV. Preliminary results of the E93-017
experiment from the analysis of the 30% of the total statistic accumulated show
persistent forward-backward asymmetry and are well described by the recent
calculation of the deuteron photodisintegration cross section derived in the
framework of the Quark Gluon String Model.
