Observing the Minkowskian dynamics of the pion on the null-plane
W. de Paula, E. Ydrefors, J. H. Alvarenga Nogueira +2
A dynamical model is applied to the study of the pion valence light-front wave function, obtained from the actual solution of the Bethe-Salpeter equation in Minkowski space, resort…
Cold atom-dimer reaction rates with He, Li and Na
Mahdi A. Shalchi, Marcelo T. Yamashita, Tobias Frederico +1
Atom-dimer exchange and dissociation reaction rates are predicted for different combinations of two He atoms and one of the alkaline species among Li, Li and $^{23}…
Modeling Dark Matter Halos with Nonlinear Field Theories
R. A. C. Correa, P. H. R. S. Moraes, A. de Souza Dutra +3
In the present work, we adopt a nonlinear scalar field theory coupled to the gravity sector to model galactic dark matter. We found analytical solutions for the scalar field couple…
The soft-gluon limit and the infrared enhancement of the quark-gluon vertex
Orlando Oliveira, Tobias Frederico, Wayne de Paula
The Schwinger-Dyson quark equation (SDE) combined with results from lattice simulation for the propagators are used to obtain information on the quark-gluon vertex, taking into acc…
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…
CP asymmetry from hadronic charm rescattering in decays at the high mass region
I. Bediaga, T. Frederico, P. C. Magalhaes
A model for the decay amplitude is proposed to study the large CP violation observed at the high mass region of the Dalitz plane. A short distance $ b \to u…
