Commutative and Noncommutative Gauge Fields
, 1999
"... The worldvolume theory on a Dbrane in a constant Bfield background can be described by either commutative or noncommutative YangMills theories. These two descriptions correspond to two different gauge fixing of the diffeomorphism on the brane. Comparing the boundary states in the two gauges, we ..."

On the geometry of noncommutative gauge fields
"... Our goal is to find a proper formulation of noncommutative gauge field theories; we do this by studying an example of a noncommutative 4dimensional sphere S4θ; it is the base space of a noncommutative principal bundle: SU(2) → S7θ → S4θ This is a quantization of the Hopf fibration on the commutativ ..."

Noncommutative Gauge Fields and Mass Generation
, 2004
"... It is well known that a typical YangMills Gauge Field is mediated by massless Bosons. It is only through a symmetry breaking mechanism, as in the SalamWeinberg model that the quanta of such an interaction field acquire a mass in the usual theory. Here we demonstrate that without taking recourse to ..."

to the usual symmetry breaking mechanism, it is possible to have massive Gauge Fields, given a noncommutative geometrical underpinning for spacetime. 1
Noncommutative Gauge Fields on Poisson Manifolds ∗
, 1999
"... It is shown by Connes, Douglas and Schwarz that gauge theory on noncommutative torus describes compactifications of Mtheory to tori with constant background threeform field. This indicates that noncommutative gauge theories on more general manifolds also can be useful in string theory. We discuss ..."

The energymomentum tensor in noncommutative gauge field models
 Int. J. Mod. Phys. A
"... Abstract. We discuss the different possibilities of constructing the various energymomentum tensors for noncommutative gauge field models. We use Jackiw’s method in order to get symmetric and gauge invariant stress tensors—at least for commutative gauge field theories. The noncommutative counterpar ..."

Nonabelian noncommutative gauge fields and SeibergWitten
, 2001
"... Noncommutative gauge fields (similar to the type that arises in string theory with background Bfields) are constructed for arbitrary nonabelian gauge groups with the help of a map that relates ordinary nonabelian and noncommutative gauge theories (SeibergWitten map). As in our previous work we emp ..."

"... gauge field theories Arguments arising from quantum mechanics and gravitation theory as well as from string theory, indicate that the description of spacetime as a continuous manifold is not adequate at very short distances. An important candidate for the description of spacetime at such scales is ..."

Renormalizability and Phenomenology of θexpanded Noncommutative Gauge Field Theory

"... In this article we consider θexpanded noncommutative gauge field theory, constructed at the first order in noncommutative parameter θ, as an effective, anomaly free theory, with oneloop renormalizable gauge sector. Related phenomenology with emphasis on the standard model forbidden decays, is disc ..."
