Hadron optics in three-dimensional invariant coordinate space from deeply virtual Compton scattering

The Fourier transform of the deeply virtual Compton scattering amplitude (DVCS) with respect to the skewness parameter zeta=Q(2)/2p center dot q can be used to provide an image of the target hadron in the boost-invariant variable sigma, the coordinate conjugate to light-front time tau=t+z/c. As an illustration, we construct a consistent c...更多
