Generalized parton distributions and double distributions for q q-bar pions
B. C. Tiburzi, G. A. Miller
We consider two simple covariant models for pions (one with scalar and the other with spin-1/2 constituents). Pion generalized parton distributions are derived by integration over…
Current in the light-front Bethe-Salpeter formalism II: Applications
B. C. Tiburzi, G. A. Miller
We pursue applications of the light-front reduction of current matrix elements in the Bethe-Salpeter formalism. The normalization of the reduced wave function is derived from the c…
Current in the light-front Bethe-Salpeter formalism I: Replacement of non-wave function vertices
B. C. Tiburzi, G. A. Miller
We apply the light-front reduction of the Bethe-Salpeter equation to matrix elements of the electromagnetic current between bound states. Using a simple (1+1)-dimensional model to…
Generalized parton distributions for pions
B. C. Tiburzi, G. A. Miller
We use a two-body, light-cone pion wave function (which vanishes when one of the constituents carries all of the plus-momentum) to construct a double distribution. We show that the…
Generalized parton distributions for weakly bound systems from light-front quantum mechanics
B. C. Tiburzi
We present generalized parton distributions for weakly bound systems on the light cone in order to build intuition about the light-front formalism. Physics at the crossover is revi…
Light front Bethe-Salpeter equation applied to form factors, generalized parton distributions and generalized distribution amplitudes
B. C. Tiburzi, G. A. Miller
We present an intuitive, light front reduction scheme for the Bethe-Salpeter equation that consists of iterations of the (light front) energy dependent covariant equation followed…
