Quark stars in - holographic model
M. Aleixo, C. H. Lenzi, W. de Paula +1
This work investigates static and dynamical quark star properties within a holographic model. We solve the Tolman-Oppenheimer-Volkoff equations for the quark matter equat…
Kaon Structure in the Nuclear Medium within the Light Front Approach
G. H. S. O. Yabusaki, J. P. B. C. de Melo, K. Tsushima +2
We study the properties of the charged kaon in symmetric nuclear matter using a Bethe-Salpeter amplitude to model the quark-anti-quark bound state, which is well constrained by pre…
A dynamical holographic QCD model for spontaneous chiral symmetry breaking and confinement
Alfonso Ballon-Bayona, Tobias Frederico, Luis A. H. Mamani +1
In this paper, we present a holographic realization of spontaneous chiral symmetry breaking and confinement. The latter is realized by building a solution of 5d Einstein-dilaton gr…
Axion stars in MGD background
R. Casadio, R. da Rocha
The minimal geometric deformation (MGD) paradigm is here employed to survey axion stars on fluid branes. The finite value of the brane tension provides beyond-general relativity co…
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…
The chiral limit of a fermion-scalar system in covariant gauges
A. Noronha, W. de Paula, J. H. de Alvarenga Nogueira +3
The homogeneous Bethe-Salpeter equation (BSE) of a (1/2) bound system, that has both fermionic and bosonic degrees of freedom, that we call a {\em mock nucleon}, is studied in…
Configurational information measure of mesonic states in 4-flavor AdS/QCD
G. Karapetyan, W. de Paula, R. da Rocha
Strange axial-vector kaons, , and meson resonances are investigated in the 4-flavor AdS/QCD model. Their underlying differential configurational entropy is computed and…
Unpolarized transverse-momentum dependent distribution functions of a quark in a pion with Minkowskian dynamics
E. Ydrefors, W. de Paula, T. Frederico +1
The unpolarized twist-2 (leading) and twist-3 (subleading), T-even, transverse-momentum dependent quark distributions in the pion are evaluated for the first time by using the actu…
