Abstract

We calculate timelike virtual Compton scattering amplitudes in the generalized Bjorken scaling regime and focus on a new polarization asymmetry in the scattering process with a linearly polarized photon beam in the medium energy range, which will be studied intensely at JLab12 experiments. We demonstrate that new observables help us to access the polarized quark and gluon generalized parton distributions H~(x,ξ,t)\tilde H(x, \xi, t) and E~(x,ξ,t) \tilde E(x, \xi, t).
