A renormalization group invariant scalar glueball operator in the (Refined) Gribov-Zwanziger framework
David Dudal, Silvio Paolo Sorella, Nele Vandersickel +1
This paper presents a complete algebraic analysis of the renormalizability of the operator in the Gribov-Zwanziger (GZ) formalism as well as in the Refined Gribov-…
Gribov horizon and BRST symmetry: a few remarks
S. P. Sorella
The issue of the BRST symmetry in presence of the Gribov horizon is addressed in Euclidean Yang-Mills theories in the Landau gauge. The positivity of the Faddeev-Popov operator wit…
A purely algebraic construction of a gauge and renormalization group invariant scalar glueball operator
D. Dudal, S. P. Sorella, N. Vandersickel +1
This paper presents a complete algebraic proof of the renormalizability of the gauge invariant operator to all orders of perturbation theory in pure Yang-Mills…
Study of the Gribov region in Euclidean Yang-Mills theories in the maximal Abelian gauge
M. A. L. Capri, A. J. Gomez, V. E. R. Lemes +2
The properties of the Gribov region in SU(2) Euclidean Yang-Mills theories in the maximal Abelian gauge are investigated. This region turns out to be bounded in all off-diagonal di…
Soft breaking of BRST invariance for introducing non-perturbative infrared effects in a local and renormalizable way
L. Baulieu, S. P. Sorella
The possibility of introducing non-perturbative infrared effects leading to a modification of the long distance behavior of gauge theories through a soft breaking of the BRST invar…
A refinement of the Gribov-Zwanziger approach in the Landau gauge: infrared propagators in harmony with the lattice results
David Dudal, John Gracey, Silvio Paolo Sorella +2
Recent lattice data have reported an infrared suppressed, positivity violating gluon propagator which is nonvanishing at zero momentum and a ghost propagator which is no longer enh…
