Axial-Vector Duality as a Mirror Symmetry
نویسنده
چکیده
We study N = 2 supersymmetric SU(2)/U(1) and SL(2, R)/U(1) gauged WessZumino-Witten models. It is shown that the vector gauged model is transformed to the axial gauged model by a mirror transformation. Therefore the vector gauged model and the axial gauged model are equivalent as N = (2, 2) superconformal field theories. In the SL(2, R)/U(1) model, it is known that axial-vector duality relates a background with a singularity to that without a singularity. Implications of the equivalence of these two models to space-time singularities are discussed. e-mail address: [email protected]

Axial-Vector Duality as a Gauge Symmetry and Topology Change in String Theory
Lines generated by marginal deformations of WZW models are considered. The Weyl symmetry at the WZW point implies the existence of a duality symmetry on such lines. The duality is interpreted as a broken gauge symmetry in string theory. It is shown that at the two end points the axial and vector cosets are obtained. This shows that the axial and vector cosets are equivalent CFTs both in the com...
متن کاملConstraining Quark - Hadron Duality at Large
Quark-meson duality for two-point functions of vector and axial-vector QCD currents is investigated in the large-Nc approximation. We find that the joint constraints of duality and chiral symmetry imply degeneracy of excited vector and axial-vector mesons in the large-Nc limit. We compare model-independent constraints with expectations based on the VenezianoLovelace-Shapiro string model. Severa...
متن کاملA New Duality Symmetry in String Theory
We consider the conformal gauging of non-abelian groups. In such cases there are inequivalent ways of gauging (generalizing the axial and vector cases for abelian groups) corresponding to external automorphisms of the group. Different σ-models obtained this way correspond to the same conformal field theory. We use the method of quotients to formulate this equivalence as a new duality symmetry. ...

Charge symmetry breaking potentials due to the exchange of pseudoscalar and vector mesons in mirror nuclei are considered. With the computation of coulmb energy along with the present charge symmetry breaking effects provide a reasonably accurate description of the binding energy differences between mirror nuclei.
متن کاملMirror Symmetry and Polar Duality of Polytopes
This expository article explores the connection between the polar duality from polyhedral geometry and mirror symmetry from mathematical physics and algebraic geometry. Topics discussed include duality of polytopes and cones as well as the famous quintic threefold and the toric variety of a reflexive polytope.
