Vector-mesons production and DVCS at Jlab
- Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States)
Deeply virtual exclusive reactions offer an unique opportunity to study the structure of the nucleon at the parton level as one has access to Bjorken xB and momentum transfer to the nucleon t at the same time. Such processes can reveal much more information about the structure of the nucleon than either inclusive electroproduction or elastic form factors alone. Dedicated experiments to study Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP) have been carried out at Jefferson Lab. DVCS helicity?dependent and helicity?independent cross sections and beam spin asymmetries have been measured with CLAS, as well as cross sections and asymmetries for the r0, r+, w and f for exclusive electroproduction. The data were taken in a wide kinematic range in Q2=1?4.5 GeV2, xB=0.1?0.5, and |t| up to 2 GeV2.
