Padé approximation and glueball mass estimates in 3d and 4d with N_c = 2,3 colors
D. Dudal, M. S. Guimaraes, S. P. Sorella
A Padé approximation approach, rooted in an infrared moment technique, is employed to provide mass estimates for various glueball states in pure gauge theories. The main input in t…
Study of the zero modes of the Faddeev-Popov operator in the maximal Abelian gauge
M. A. L. Capri, M. S. Guimaraes, V. E. R. Lemes +2
A study of the zero modes of the Faddeev-Popov operator in the maximal Abelian gauge is presented in the case of the gauge group SU(2) and for different Euclidean space-time dimens…
The (IR-)relevance of the Gribov ambiguity in SU(2) x U(1) gauge theories with fundamental Higgs matter
M. A. L. Capri, D. Dudal, M. S. Guimaraes +3
It is well accepted that dealing with the Gribov ambiguity has a major impact on correlation functions in gauge-fixed Yang-Mills theories, in particular in the low momentum regime…
The Chern-Simons term in a dual Josephson junction
L. S. Grigorio, M. S. Guimaraes, R. Rougemont +2
A dual Josephson junction corresponding to a (2+1)-dimensional non-superconducting layer sandwiched between two (3+1)-dimensional dual superconducting regions constitutes a model o…
Spontaneous breaking of the BRST symmetry in presence of the Gribov horizon: renormalizability
M. A. L. Capri, D. Dudal, M. S. Guimaraes +3
An all orders algebraic proof of the multiplicative renormalizability of the novel formulation of the Gribov-Zwanziger action proposed in Phys. Rev. D 86, 045005 (2012) [arXiv:1205…
SU(2) x U(1) Yang-Mills theories in 3d with Higgs field and Gribov ambiguity
M. A. L. Capri, D. Dudal, M. S. Guimaraes +3
We study the structure of the gauge propagators of a 3d version of the electroweak interaction in terms of the Higgs vacuum expectation value nu, of the non-Abelian gauge coupling…
