Exploring the bound state with dressed quarks in Minkowski space
A. Castro, W. de Paula, E. Ydrefors +2
The Bethe-Salpeter equation for a pseudoscalar bound-system, with i) a ladder kernel with massive gluons, ii) dynamically-dressed quark mass function and iii) an extended quark-glu…
Proton quark distributions from a light-front Faddeev-Bethe-Salpeter approach
Emanuel Ydrefors, Tobias Frederico
The projection onto the Light-Front of a Minkowski space Faddeev-Bethe-Salpeter equation model truncated at the valence level is applied to study the proton structure with constitu…
Dynamical mass generation in Minkowski space at QCD scale
Dyana C. Duarte, Tobias Frederico, Wayne de Paula +1
We undertake the challenging task to reveal the properties of dressed light-quarks in the space- and time-like regions. For that aim, we solved the Dyson-Schwinger equation (DSE) i…
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…
Protonium annihilation densities in a unitary coupled channel model
Emanuel Ydrefors, Jaume Carbonell
We consider a unitary coupled channel model to describe the low energy proton-antiproton scattering and the lower Coulomb-like protonium states. The existence of deeper quasi-bound…
Proton image and momentum distributions from light-front dynamics
Emanuel Ydrefors, Tobias Frederico
We apply a dynamical three-constituent quark light-front model to study the proton. The dynamics is based on the notion of a diquark (bound or virtual) as the dominant interaction…
