Spontaneous symmetry breaking as a mechanism for the Gribov scale in a BRST-invariant formulation
M. A. L. Capri, V. E. R. Lemes
We propose a BRST-invariant formulation of the Gribov--Zwanziger model in the Landau gauge, in which the Gribov scale is produced by the spontaneous breaking of a scalar quartet sy…
A Gauge Theory of Turbulence:
V. E. R. Lemes
We formalize the gauge structure of the Navier--Stokes equation for incompressible fluids, interpreting as a gauge fixing analogous to the Coulomb gauge i…
Pathways to Real Composite Operators from Non-Hermitian Fermions
V. E. R. Lemes, D. G. Tedesco
A field theory in dimensions contains two fermions, two Abelian gauge fields, and one complex scalar, with dynamics fixed by a BRST symmetry. For a specific parameter configu…
Background-Equivariant BRST Observables and i-Particle Propagators from an Auxiliary Quartet in SU(3) Yang-Mills
M. M. Amaral, V. E. R. Lemes
We construct a BRST-exact quartet mechanism in Yang-Mills theory in the Landau gauge. The quartet sector is cohomologically trivial in the standard vacuum, ensuring equival…
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…
