On the SL(2,R) symmetry in Yang-Mills Theories in the Landau, Curci-Ferrari and Maximal Abelian Gauge
D. Dudal, V. E. R. Lemes, M. Picariello +3
The existence of a SL(2,R) symmetry is discussed in SU(N) Yang-Mills in the maximal Abelian Gauge. This symmetry, also present in the Landau and Curci-Ferrari gauge, ensures the ab…
The mass gap and vacuum energy of the Gross-Neveu model via the 2PPI expansion
David Dudal, Henri Verschelde
We introduce the 2PPI (2-point-particle-irreducible) expansion, which sums bubble graphs to all orders. We prove the renormalizibility of this summation. We use it on the Gross-Nev…
On ghost condensation, mass generation and Abelian dominance in the Maximal Abelian Gauge
David Dudal, Henri Verschelde
Recent work claimed that the off-diagonal gluons (and ghosts) in pure Yang-Mills theories, with Maximal Abelian gauge fixing (MAG), attain a dynamical mass through an off-diagonal…
Dynamical mass generation in quantum field theory : some methods with application to the Gross-Neveu model and Yang-Mills theory
D. Dudal, K. Van Acoleyen, H. Verschelde
We introduce some techniques to investigate dynamical mass generation. The Gross-Neveu model (GN) is used as a toy model, because the GN mass gap is exactly known, making it possib…
