Singular gauge transformations and supersymmetry breakdown on warped orbifolds

High Energy Physics - Theory 2009-11-10 v2

Abstract

We have analyzed the breakdown of global supersymmetry by a non-vanishing expectation value of the fifth component of the graviphoton on warped S^1/Z_2 orbifolds. It has been demonstrated that the setups where such a breakdown is possible correspond to the models where the true gauge symmetry on the orbifold, respecting the Z_2-parities and periodicity, is broken by boundary terms. In the tuned models, giving Randall-Sundrum warp factor, gauge symmetry stays intact, and any <A_5> can be gauged away without violating supersymmetry.
