Low energy Eta-baryon interaction
Marcelo G. L. Nogueira-Santos, Celso C. Barros
The -Baryon interactions at low energies are studied in a model based in effective chiral Lagragians that take into account baryons of spin 1/2 and spin 3/2 in the intermediate…
Spin-0 bosons near rotating stars
Eduardo O. Pinho, Celso C. Barros
In this work we study the effects of rotating stars on the behavior of bosons close to their surfaces. For this task, metrics determined by the rotation of these stars will be take…
Fluctuations in the pasta phase
Mateus R. Pelicer, Débora P. Menezes, Celso C. Barros +1
Baryonic matter close to the saturation density is very likely to present complex inhomogeneous structures collectively known under the name of pasta phase. At finite temperature,…
Rapidly rotating compact stars in Rastall's gravity
F. M. da Silva, L. C. N. Santos, C. C. Barros
In this work we study rapidly rotating stars by considering the Rastall theory of gravity. We obtain and solve the equations by numerical methods for two usual parametrization of p…
Low energy pion- interaction
Marcelo G. L. Nogueira-Santos, Celso C. Barros
In this work we study the low energy pion- interaction considering effecective chiral Lagrangians that include pions, baryons and the corresponding resonances. Interactions me…
Quantum dynamics of scalar particles in the space-time of a cosmic string in the context of gravity's rainbow
L. C. N. Santos, C. E. Mota, C. C. Barros +2
We analyze the dynamics of scalar particles in gravity's rainbow considering the space-time of a cosmic string in this modified gravity. Thus, we solve the Klein-Gordon equation fo…
