The parton distribution function in a pion with Minkowskian dynamics
W. de Paula, E. Ydrefors, J. H. Alvarenga Nogueira +2
The parton distribution of the pion is obtained for the first time from the solution of a dynamical equation in Minkowski space. The adopted equation is the homogeneous Bethe-Salpe…
Pion electromagnetic form factor with Minkowskian dynamics
Emanuel Ydrefors, Wayne de Paula, Jorge H Alvarenga Nogueira +2
The pion electromagnetic form factor has been calculated for the first time from the solutions of the Bethe-Salpeter equation, obtained directly in Minkowski space by using the Nak…
Three-boson bound states in Minkowski space with contact interactions
E. Ydrefors, J. H. Alvarenga Nogueira, V. A. Karmanov +1
The structure of the three-boson bound state in Minkowski space is studied for a model with contact interaction. The Faddeev-Bethe-Salpeter equation is solved both in Minkowski and…
Solving the Bethe-Salpeter Equation in Minkowski Space for a Fermion-Scalar system
J. H. Alvarenga Nogueira, D. Colasante, V. Gherardi +3
The ladder Bethe-Salpeter Equation of a bound (1/2)+ system, composed by a fermion and a scalar boson, is solved in Minkowski space, for the first time. The formal tools are the sa…
Solving the three-body bound-state Bethe-Salpeter equation in Minkowski space
E. Ydrefors, J. H. Alvarenga Nogueira, V. A. Karmanov +1
The scalar three-body Bethe-Salpeter equation, with zero-range interaction, is solved in Minkowski space by direct integration of the four-dimensional integral equation. The singul…
