Measurements of Deeply Virtual Exclusive ρ0 Production with CLAS12

ORAL

Abstract



The CLAS12 detector at Jefferson Lab was used to study deeply virtual exclusive ρ0 electroproduction. Data was collected with a 10.6 GeV polarized electron beam on an unpolarized liquid hydrogen target. A large sample of statistics, allowed for multidimensional measurements of beam spin asymmetry of the ρ0 over the large kinematic ranges in xb , -t, and Q2. Using multidimensional binning, the sinΦ moment, ALUsinΦ, was calculated. Accessing these moments will give a deeper insight, at a leading twist level, of unpolarized Generalized Parton Distributions (GPDs), H and E, and at the next leading twist level, of chiral odd GPDs. The status of this ongoing analysis will be presented.
