Are the Theta+(1540), Xi--(1860) and D*-p(3100) Pentaquarks or Heptaquarks?
P. Bicudo
We study the Theta+(1540) discovered at SPring-8. We apply Quark Model techniques, that explain with success the repulsive hard core of nucleon-nucleon and kaon-nucleon exotic scat…
The pomeron conjecture and two gluon glueballs
P. Bicudo
In this talk the pomeron conjecture is reviewed and constituent gluon models are derived. In a simple two-gluon glueball spectrum the pomeron trajectory and the daughter trajectori…
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…
Analytic proof of the Weinberg theorem for off mass shell and composite pions
Pedro Bicudo
The Weinberg theorem for the pion-pion scattering is proved analytically in full detail for quark models in the ladder truncation. The proof is displayed with Feynman diagrams. The…
Criterium for the index theorem on the lattice
Pedro J. de A. Bicudo
We study how far the Index Theorem can be extrapolated from the continuum to finite lattices with finite topological charge densities. To examine how the Wilson action approximates…
The scalar meson puzzle beyond BCS
Pedro Bicudo
Les We present a new perspective on the scalar meson puzzle from spontaneous breaking of chiral symmetry beyond BCS. We find that going beyond BCS does not produce a systematic shi…
