Bethe-Salpeter bound-state structure in Minkowski space
C. Gutierrez, V. Gigante, T. Frederico +3
The quantitative investigation of the scalar Bethe-Salpeter equation in Minkowski space, within the ladder-approximation framework, is extended to include the excited states. This…
Solution of Two-Body Bound State Problems with Confining Potentials
M. R. Hadizadeh, Lauro Tomio
The homogeneous Lippmann-Schwinger integral equation is solved in momentum space by using confining potentials. Since the confining potentials are unbounded at large distances, the…
Electromagnetic structure and weak decay of meson K in a light-front QCD-inspired
Fabiano P. Pereira, J. P. B. C. de Melo, T. Frederico +1
The kaon electromagnetic (e.m.) form factor is reviewed considering a light-front constituent quark model. In this approach, it is discussed the relevance of the quark-antiquark pa…
Kaon Eletromagnetic Form Factor in the Light-Front Formalism
Fabiano P. Pereira, J. P. B. C. de Melo, T. Frederico +1
Numerical calculations are performed and compared to the experimental data for the electromagnetic form factor of the kaon, which is extracted from both components of the electroma…
Path Dependence of the Quark Nonlocal Condensate within the Instanton Model
L. A. Trevisan, A. E. Dorokhov, Lauro Tomio
Within the instanton liquid model, we study the dependence of the gauge invariant two--point quark correlator on the path used to perform the color parallel transport between two p…
Light-front model of the kaon electromagnetic current
J. P. B. C. de Melo, Lauro Tomio, T. Frederico
The electromagnetic form factor is extracted from both components of the electromagnetic current: J(plus) and J(minus) with a pseudo-scalar coupling of the quarks to the kaon. In t…
