Light-cone gauge integrals: prescriptionlessness at two loops
(Elsevier B.V., 2000-11-30)
The only calculations performed beyond one-loop level in the light-cone gauge make use of the Mandelstam-Leibbrandt (ML) prescription in order to circumvent the notorious gauge dependent poles. Recently we have shown that ...

Comments on regularization ambiguities and local gauge symmetries
(World Scientific Publ Co Pte Ltd, 2005-08-20)
We study the regularization ambiguities in an exact renormalized (1 + 1)-dimensional field theory. We show a relation between the regularization ambiguities and the coupling parameters of the theory as well as their role ...

Remarks on entanglement entropy for gauge fields
(Amer Physical Soc, 2013-12)
In gauge theories the presence of constraints can obstruct expressing the global Hilbert space as a tensor product of the Hilbert spaces corresponding to degrees of freedom localized in complementary regions. In ...

Loop Integrals in Three Outstanding Gauges: Feynman, Light-Cone, and Coulomb
(2001-03-20)
We apply the negative dimensional integration method (NDIM) to three outstanding gauges: Feynman, light-cone, and Coulomb gauges. Our aim is to show that NDIM is a very suitable technique to deal with loop integrals, ...
QUASI-TOPOLOGICAL QUANTUM FIELD THEORIES AND Z(2) LATTICE GAUGE THEORIES
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2012)
We consider a two-parameter family of Z(2) gauge theories on a lattice discretization T(M) of a three-manifold M and its relation to topological field theories. Familiar models such as the spin-gauge model are curves on a ...
