Seiberg-Witten for Spin(n) with spinors
(Springer, 2015-08-07)
N = 2 supersymmetric Spin(n) gauge theory admits hypermultiplets in spinor representations of the gauge group, compatible with beta <= 0, for n <= 14. The theories with beta < 0 can be obtained as mass-deformations of the ...
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 ...

Ghost free dual vector theories in 2+1 dimensions
(Int School Advanced Studies, 2006-01-01)
We explore here the issue of duality versus spectrum equivalence in dual theories generated through the master action approach. Specifically we examine a generalized self-dual (GSD) model where a Maxwell term is added to ...
Second order gauge theory
(Elsevier B.V., 2007-05-01)
A gauge theory of second order in the derivatives of the auxiliary field is constructed following Utiyama's program. A novel field strength G = partial derivative F + fAF arises besides the one of the first order treatment, ...

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 ...

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, ...
