Dynamical gluon mass generation from <A^2> in linear covariant gauges
D. Dudal, H. Verschelde, J. A. Gracey +4
We construct the multiplicatively renormalizable effective potential for the mass dimension two local composite operator A^2 in linear covariant gauges. We show that the formation…
A non-commutative n-particle 3D Wigner quantum oscillator
R. C. King, T. D. Palev, N. I. Stoilova +1
An n-particle 3-dimensional Wigner quantum oscillator model is constructed explicitly. It is non-canonical in that the usual coordinate and linear momentum commutation relations ar…
The 2PPI expansion: dynamical mass generation and vacuum energy
D. Dudal, H. Verschelde, R. E. Browne +1
We discuss the 2PPI expansion, a summation of the bubble graphs up to all orders, by means of the 2D Gross-Neveu toy model, whose exact mass gap and vacuum energy are known. Then w…
Renormalizability of the local composite operator A^2 in linear covariant gauges
D. Dudal, H. Verschelde, V. E. R. Lemes +4
The local composite operator is analysed within the algebraic renormalization in Yang-Mills theories in linear covariant gauges. We establish that it is multiplicatively…
Vacuum Condensates and Dynamical Mass Generation in Euclidean Yang-Mills Theories
D. Dudal, H. Verschelde, V. E. R. Lemes +6
Vacuum condensates of dimension two and their relevance for the dynamical mass generation for gluons in Yang-Mills theories are discussed
The anomalous dimension of the gluon-ghost mass operator in Yang-Mills theory
D. Dudal, H. Verschelde, V. E. R. Lemes +5
The local composite gluon-ghost operator is analysed in the framework of the algebraic renormalization in SU(N) Yang-Mills theories in the…
Vacuum Condensates of Dimension Two in Pure Euclidean Yang-Mills
D. Dudal, A. R. Fazio, V. E. R. Lemes +4
Gluon and ghost condensates of dimension two and their relevance for Yang-Mills theories are briefly reviewed
The non-commutative and discrete spatial structure of a 3D Wigner quantum oscillator
R. C. King, T. D. Palev, N. I. Stoilova +1
The properties of a non-canonical 3D Wigner quantum oscillator, whose position and momentum operators generate the Lie superalgebra sl(1|3), are further investigated. Within each s…
A determination of <A^2> and the non-perturbative vacuum energy of Yang-Mills theory in the Landau gauge
D. Dudal, H. Verschelde, R. E. Browne +1
We discuss the 2-point-particle-irreducible (2PPI) expansion, which sums bubble graphs to all orders, in the context of SU(N) Yang-Mills theory in the Landau gauge. Using the metho…
Gluon-ghost condensate of mass dimension 2 in the Curci-Ferrari gauge
D. Dudal, H. Verschelde, V. E. R. Lemes +3
The effective potential for an on-shell BRST invariant gluon-ghost condensate of mass dimension 2 in the Curci-Ferrari gauge in SU(N) Yang-Mills is analysed by combining the local…
The anomalous dimension of the composite operator A^2 in the Landau gauge
D. Dudal, H. Verschelde, S. P. Sorella
The local composite operator A^2 is analysed in pure Yang-Mills theory in the Landau gauge within the algebraic renormalization. It is proven that the anomalous dimension of A^2 is…
