Pseudoscalar meson mass relations from a second-order phase transition
R. L. P. G. Amaral, V. E. R. Lemes, O. S. Ventura +1
This work is divided in two parts. The first three sections review meson physics phenomenology, highlighting the history of pseudoscalar multiplet mass spectra research. We then pr…
Gribov Problem in the Eletroweak and Gluon Confined Theories
R. L. P. G. Amaral, V. E. R. Lemes, O. S. Ventura +1
We show that gauge fields after a spontaneous symmetry breaking (SSB) mechanism do not have a Gribov problem along the broken directions. In order to make this proof, we describe a…
A BRST Characterization of the Broken Phase Observables of the Confining Complex Theory
R. L. P. G. Amaral, V. E. R. Lemes, O. S. Ventura +1
Some time ago we have introduced a route to provide confinement in the sense that particle excitations would appear from condensates of fields that do not have physical asymptotic…
A BRST view of the spontaneous symmetry breaking
R. L. P. G. Amaral, V. E. R. Lemes, O. S. Ventura +1
After the phase transition of a Grand Unified Theory (GUT), its single coupling splits into the couplings of the basic interactions. On the other side, the measurement of the Weinb…
A path to confine gluons and fermions through complex gauge theory
R. L. P. G. Amaral, V. E. R. Lemes, O. S. Ventura +1
We introduced here the study of a QCD based on a complex group. Our aim is to show that a gauge theory with a complex symmetry develops some of the features required for the descri…
Confining Potentials
R. L. P. G. Amaral, V. E. R. Lemes, O. S. Ventura +1
We use the t'Hoft-Wilson method for the generation of static fermions potential in order to derive a class of confining potentials which can describe the quark confinement. A gener…
