Axions and a Gauged Peccei-Quinn Symmetry
The axion solution to the strong CP problem requires an anomalous global U(1) symmetry. We show that the existence of such a symmetry is a natural consequence of an extra dimension in which a gauged U(1) is spontaneously broken on one of two branes, leaving an accidental global symmetry on the other brane. Depending on where the standard model matter lives, the resulting axion can be either the...
متن کاملPatterns of Symmetry Breaking in Gauged Supersymmetric Sigma Mcjdels
We consider supersymmetric nonlinear sigma models, in which the chiral superfields-serve as coordinates on a compact coset space G/H, and study the effects of gauging various subgroups S C G. The general result is that S spontaneously breaks down much more than expected from experience with nonsupersymmetric models. In particular the rank of S is almost never preserved. Significantly, if S is l...
متن کاملAnomaly-Free Gauged R-Symmetry in Local Supersymmetry
We discuss local R-symmetry as a potentially powerful new model building tool. We first review and clarify that a U(1) R-symmetry can only be gauged in local and not in global supersymmetry. We determine the anomaly-cancellation conditions for the gauged R-symmetry. For the standard superpotential these equations have no solution, independently of how many Standard Model singlets are added to t...
متن کاملGauged Duality, Conformal Symmetry and Spacetime with Two Timesa
We construct a duality between several simple physical systems by showing that they are different aspects of the same quantum theory. Examples include the free relativistic massless particle and the hydrogen atom in any number of dimensions. The key is the gauging of the Sp(2) duality symmetry that treats position and momentum (x, p) as a doublet in phase space. As a consequence of the gauging,...
متن کاملConsequences of Supergravity with Gauged U ( 1 ) R Symmetry
The structure of gauged R supergravity Lagrangians is reviewed, and we consider models with a hidden sector plus light fields of the MSSM. A simple potential for the hidden sector is presented which has a global minimum with zero cosmological constant and spontaneously broken SUSY and R-symmetry. The U(1) R vector multiplet acquires a Planck scale mass through the Higgs mechanism, and it decoup...
