Bound state structure and electromagnetic form factor beyond the ladder approximation
(2017-03-01)
We investigate the response of the bound state structure of a two-boson system, within a Yukawa model with a scalar boson exchange, to the inclusion of the cross-ladder contribution to the ladder kernel of the Bethe-Salpeter ...
Antiparticle Contribution in the Cross Ladder Diagram for Bethe-Salpeter Equation in the Light-Front
(Springer/plenum Publishers, 2009-11-01)
We construct the homogeneous integral equation for the vertex of the bound state in the light front with the kernel approximated to order g(4). We will truncate the hierarchical equations from Green functions to construct ...

Phase diagram study of a dimerized spin-S zig–zag ladder
(IOP Publishing, 2014-07)
The phase diagram of a frustrated spin-S zig–zag ladder is studied through different numerical and analytical methods. We show that for arbitrary S, there is a family of Hamiltonians for which a fully-dimerized state is ...

Cross-Ladder Diagrams Via Hierarchical Equations in the Light Front
(Springer, 2015-09-01)
We calculate the correction to the propagator of two bosons up to the g (4) order in the cross-ladder approximation in the light front. The hierarchy of the coupled equations describe the propagator of two bosons in various ...

Relativistic three-body model for final state interaction in D+ → K-π+π+ decay
(2010-12-01)
A challenge in mesonic three-body decays of heavy mesons is to quantify the contribution of re-scattering between the final mesons. D decays have the unique feature that make them a key to light meson spectroscopy, in ...
