Sound waves and solitons in hot and dense nuclear matter
D. A. Fogaça, L. G. Ferreira Filho, F. S. Navarra
Assuming that nuclear matter can be treated as a perfect fluid, we study the propagation of perturbations in the baryon density. The equation of state is derived from a relativisti…
Korteweg - de Vries solitons in relativistic hydrodynamics
D. A. Fogaça, F. S. Navarra
In a previous work, assuming that the nucleus can be treated as a perfect fluid, we have studied the propagation of perturbations in the baryon density. For a given equation of sta…
Solitons in relativistic mean field models
D. A. Fogaça, F. S. Navarra
Assuming that the nucleus can be treated as a perfect fluid we study the conditions for the formation and propagation of Korteweg-de Vries (KdV) solitons in nuclear matter. The KdV…
Can the meson cloud explain the nucleon strangeness?
Fabiana Carvalho, Fernando S. Navarra, Marina Nielsen
We use the meson cloud model, including the kaon and the contributions, to estimate the electric and magnetic strange form factors of the nucleon. We compare our results with…
A QCD Sum Rule Study of in Nuclear Matter
F. S. Navarra, M. Nielsen, K. Tsushima
We consider a current, in the finite-density QCD sum rule approach, to investigate the scalar and vector self-energies of the recently observed pentaquark state $Θ^…
Meson loop effects on the pion electromagnetic form factor
F. Carvalho, F. O. Durães, F. S. Navarra +1
In this work we calculate the meson loop effects on the pion electromagnetic form factor and perform a comparison with experimental data. We show that, even though the meson cloud…
