Abstract: FE.00004 : Exclusive neutral pion electro-production cross-sections from experiment E12-06-114 at JLab 12 GeV*
9:45 AM–10:00 AM
Generalized Parton Distribution (GPDs) functions describe the correlation between the spatial distribution of the quarks and its longitudinal momentum fraction. Their definition in the mid 1990's has revolutionized our approach to the description of the internal structure of the nucleon. The study of the GPDs together with the study of similar quantities are at the fore-front of today hadronic physics enterprise. In consequences, deeply virtual photon (DVCS) and meson (DVMP) electroproduction have attracted much interest. In this talk, I will present neutral pion production cross-sections measured in Hall A at Jefferson Lab with the newly updated electro beam. These data will extend the Q2 range at xBjorken=0.36 up to 4.5 GeV2. They will further test the limits of factorization concepts essential to the introduction of the GPD concept. They will also further test model that uses transversity GPDs to describe data at lower Q2.
