Gauge Invariant Action at the Ultraviolet Cutoff *

We show that it is possible to formulate a gauge theory starting from a local action at the ultraviolet (UV) momentum cutoff which is BRS invariant. One has to require that fields in the UV action and the fields in the effective action are not the same but related by a local field transformation. The few relevant parameters involved in this transformation (six for the SU(2) gauge theory), are p...

Remarks on Gauge-Invariant Variables and Interaction Energy in QED

The calculation of the interaction energy in pure QED and Maxwell-ChernSimons gauge theory is re-examined by exploiting the path dependence of the gauge-invariant variables formalism. In particular, we consider a spacelike straight line which leads to the Poincaré gauge. Subtleties related to the problem of exhibiting explicitly the interaction energies are illustrated. Typeset using REVTEX ∗E-...

Gauge Principle and Qed *

One of the major developments of twentieth century physics has been the gradual recognition that a common feature of the known fundamental interactions is their gauge structure. In this talk the early history of gauge theory is reviewed, emphasizing especially Weyl’s seminal contributions of 1918 and 1929.

Lorentz-Invariant Non-Commutative QED

Lorentz-invariant non-commutative QED (NCQED) is constructed such that it should be a part of Lorentz-invariant non-commutative standard model (NCSM), a subject to be treated in later publications. Our NCSM is based on Connes’ observation that the total fermion field in the standard model may be regarded as a bi-module over a flavorcolor algebra. In this paper, it is shown that there exist two ...

The Static Gauge Potential with a Cutoff

The static potential, corresponding to the interaction of two heavy sources is computed forN = 4 Super Yang Mills in the strong ’t Hooft coupling regime by using the AdS/CFT conjecture and performing a computation of a rectangular Wilson loop at a finite distance of the boundary.
