Emergent Supersymmetry in Warped Backgrounds

We show that quantum mechanical supersymmetries are emerged in Kaluza– Klein spectrum of linearized gravity in several warped backgrounds as a consequence of higher-dimensional general coordinate invariance. These emergent supersymmetries play an essential role for the spectral structure of braneworld gravity. We show that for the case of braneworld models with two codimension-1 branes the spec...

Conformal matter in warped backgrounds

Warped backgrounds in five dimensional models can provide solutions to various hierarchy problems in particle physics if the standard model matter is associated with the zero modes of bulk fields with nontrivial profiles along the extra dimension. We investigate the case of a conformally coupled massless scalar. This field possesses a zero mode whose action density is exponentially enhanced alo...

Branes and Orbifolds are Opaque

We examine localized kinetic terms for gauge fields which can propagate into compact extra dimensions. We find that such terms are generated by radiative corrections in both theories with matter fields confined to branes and in theories imposing orbifold boundary conditions on bulk matter. In both cases, the radiative corrections are logarithmically divergent, indicating that from an effective ...

Branes in Special Holonomy Backgrounds

We study the flow from the theory of D2-branes in a G2 holonomy background to M2-branes in a Spin(7) holonomy background. We consider in detail the UV and IR regimes, and the effect of topology change of the background on the field theory. We conjecture a non-Abelian N = 1 mirror symmetry.

D-Branes in Nongeometric Backgrounds

“T-fold” backgrounds are generically-nongeometric compactifications of string theory, described by T fibrations over a base N with transition functions in the perturbative T-duality group. We review Hull’s doubled torus formalism, which geometrizes these backgrounds, and use the formalism to constrain the D-brane spectrum (to leading order in gs and α ) on T fibrations over S with O(n, n;Z) mon...
