A warped supersymmetric standard model

We study the breaking of supersymmetry in five-dimensional (5d) warped spac es, using the Randall-Sundrum model as a prototype. In particular, we prese nt a supersymmetry-breaking mechanism which has a geometrical origin, and c onsists of imposing different boundary conditions between the fermions and bosons living in the 5d bulk. The scale of supersymmetry breaking is expone ntially small due to the warp factor of the AdS metric. We apply this mecha nism to a supersymmetric standard model where supersymmetry breaking is tra nsmitted through the AdS bulk to matter fields confined on the Planck brane . This leads to a predictable superparticle mass spectrum where the graviti no mass is 10(-3) eV and scalar particles receive masses at the one-loop le vel via bulk gauge interactions. We calculate the mass spectrum in full det ail using the 5d AdS propagators. The AdS/CFT correspondence suggests that our 5d warped model is dual to the ordinary 4d MSSM with a strongly coupled CFT sector responsible for the breaking of supersymmetry.
