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…
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…
More on ghost condensation in Yang-Mills theory: BCS versus Overhauser effect and the breakdown of the Nakanishi-Ojima annex SL(2,R) symmetry
D. Dudal, H. Verschelde, V. E. R. Lemes +5
We analyze the ghost condensates <f^{abc}c^{b}c^{c}>, <f^{abc}\oc^{b}\oc^{c}> and <f^{abc}\oc^{b}c^{c}> in Yang-Mills theory in the Curci-Ferrari gauge. By combining the local comp…
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
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…
