Schwinger-Dyson equations and the quark-antiquark static potential
P. Bicudo, G. Marques, M. Cardoso +2
In lattice QCD, a confining potential for a static quark-antiquark pair can be computed with the Wilson loop technique. This potential, dominated by a linear potential at moderate…
The Theta+ (1540) as an overlap of a pion, a kaon and a nucleon
P. Bicudo, G. M. Marques
We study the very recently discovered (1540) at SPring-8, at ITEP and at CLAS-Thomas Jefferson Lab. We apply the same RGM techniques that already explained with success the r…
Hard core attraction in hadron scattering and the family of the Ds meson molecule
P. Bicudo, G. M. Marques
We study the discovered Ds(2317) at BABAR, CLEO and BELLE, and find that it belongs to a class of strange multiquarks, which is equivalent to the class of kaonic molecules bound by…
Chiral Symmetry Breaking and Scalar Confinement
P. Bicudo, G. M. Marques
We address the old difficulty in accommodating the scalar quark-antiquark confining potential together with chiral symmetry breaking. We develop a quark confining potential inspire…
The effect of nonlocal confining kernels on magnetic chiral condensates
R. Gonzalez Felipe, G. M. Marques, J. E. Ribeiro
The physics of spontaneous chiral symmetry breaking in the case of the simultaneous presence of a magnetic field and a fermionic quartic interaction is discussed for both local and…
Chiral Symmetry Breaking with Scalar Confinement
P. Bicudo, G. Marques
Spontaneous chiral symmetry breaking is accepted to occur in low energy hadronic physics, resulting in the several successful theorems of PCAC. On the other hand scalar confinement…
