Supersymmetric U(1) Gauge Field Theory With Massive Gauge Field

According to the conventional notion, if a system has strict gauge symmetry, the mass of gauge field in the lagrangian must be zero [1 ]. With the development of the gauge theory, this notion has already been changed. In the gauge theory developed by Wu [2 ], under the precondition that the system has strict gauge symmetry, the theory contains massive gauge bosons. In fact, this result holds no...

× U ( 1 ) Non - anticommutative N = 2 Supersymmetric Gauge Theory 1

We derive the master function governing the component action of the four-dimensional non-anticommutative (NAC) and fully N=2 supersymmetric gauge field theory with a non-simple gauge group U(2) = SU(2) × U(1). We use a Lorentz-singlet NACdeformation parameter and an N=2 supersymmetric star (Moyal) product, which do not break any of the fundamental symmetries of the undeformed N=2 gauge theory. ...

Noncommutative U(1) Gauge Theory as a Non-linear Sigma Model

Noncommutative U (1) gauge theory in 4−dimensions is shown to be equivalent in some scaling limit to an ordinary non-linear sigma model in 2−dimensions. The model in this regime is solvable and the corresponding exact beta function is found. We also show that classical U (n) gauge theory on R d−2 ×R 2 θ can be approximated by a sequence of ordinary (d − 2)−dimensional Georgi-Glashow models with...

Generalized ensemble algorithm for U(1) gauge theory

The four dimensional pure compact U(1) gauge theory is known to posses a phase transition (PT) separating a confined phase and a Coulomb one and the determination of the order of PT is of great importance. In the pure compact U(1) gauge theory, however, the determination of the order of PT is very difficult since on large lattices the standard updating algorithms like Metropolis, heat-bath, hyb...
