Accessing proton GPDs in asymmetric frames: Numerical implementation

Abstract: In this work, we present a numerical investigation of a novel Lorentz-covariant parametrization to extract π‘₯-dependent GPDs using off-forward matrix elements of momentum-boosted hadrons coupled to non-local operators. The novelty of the method is the implementation of a asymmetric frame for the momentum transfer between the initial and final hadron state and the parametrization of the matrix elements into Lorentz-invariant amplitudes. The amplitudes can then be related to the standard light-cone GPDs. GPDs ar… Show more
