A mass-deformed BLG theory in Gribov–Zwanziger framework

Abstract

In this paper, we extend the Gribov–Zwanziger framework accounting for the existence of Gribov copies to the mass deformed Bagger–Lambert–Gustavsson (BLG) theory in [Formula: see text] superspace. The restriction of the domain of integration in the Euclidean functional integral to the first Gribov horizon is implemented, by adding a nonlocal horizon term to the effective action. Furthermore, the soft breaking of the BRST symmetry due to horizon term is restored with the help of external sources. We compute the various Ward identities for this theory relying on the Lie 3-algebras.
