Duality Beyond Global Symmetries: The Fate of the Bμν Field
نویسنده
چکیده
Duality between the ‘axion’ field a and the antisymmetric tensor field Bμν is traced after a nonperturbative effect, gaugino condensation, breaks the Peccei-Quinn (PQ) symmetry a → a + c. Even though the PQ symmetry was at its origin, duality is nevertheless not broken by this effect. Below condensation scale, the axion simply gets a mass, but in the ‘stringy’ version, the Bμν field disappears from the propagating spectrum. Its place is taken by a massive 3-index antisymmetric field Hμνρ which is the one dual to the massive axion. This is a particular case of a general duality in D-dimensions among massive p and D − p− 1-index antisymmetric tensor fields.

Gaugino Condensation, Duality and Supersymmetry Breaking
The status of gaugino condensation in low-energy string theory is reviewed. Emphasis is given to the determination of the efective action below condensation scale in terms of the 2PI and Wilson actions. We illustrate how the different perturbative duality symmetries survive this simple nonperturbative phenomenon, providing evidence for the believe that these are exact nonperturbative symmetries...
متن کاملNote on ( D 6 , D 8 ) Bound State , Massive Duality and Non - commutativity ∗
In this paper we study half-supersymmetric (D6,D8) bound state brane configuration of massive type IIA supergravity. We show this bound state can also be generated by using massive T-duality rules of type II strings in D = 9 and starting from D7-branes. We write down corresponding Killing spinors and find that these backgrounds indeed preserve 16 supersymmetries like any other Dp-brane bound st...
متن کاملS-Duality and Global Symmetries in N=2 Supersymmetric Field Theory
S-dualities in scale invariant N = 2 supersymmetric field theories are derived by embedding those theories in asymptotically free N = 2 theories with higher rank gauge groups. Sduality transformations on the coupling of the scale invariant theory follow from global symmetries acting on the Coulomb branch of the higher rank theory. Since these global symmetries are exact in the asymptotically fr...
متن کاملHeterotic effective action and duality symmetries revisited
The dimensional reduction of heterotic supergravity with gauge fields truncated to the Cartan subalgebra exhibits a continuous O(d, d+ 16;R) global symmetry, related to the O(d, d+16;Z) T-duality of heterotic strings on a d-torus. The O(d, d+16;R) symmetry is not present, however, if the supergravity reduction is done including the full set of E8×E8 or SO(32) gauge fields. We analyze which dual...
متن کاملThe Dual Faces of String
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that, for backgrounds generated from compact WZW and coset models, such duality symmetries are exact to all orders in string perturbation theory. A global treatment of duality symmetries is given, by associating them to the known symmetries of affine current algebras ( affine-Weyl group and exte...
