Title: Theoretical simulation of the virtual meson production in the forward direction

Abstract: I discuss a theoretical simulation of the virtual meson production amplitude in the forward direction using a simple scalar field model. Taking advantage of the light-front dynamics in 1+1 dimensions, I present the analysis of all the contributions including both “handbag” and “cat’s ears” for the entire kinematic regions of $Q^2>0$ and $t<0$ in the one loop level. The result from the GPD formulation is benchmarked for the estimation of the deeply virtual $-t/Q^2$ values and the GPD sum rule to provide the corresponding electromagnetic form factor is discussed.
