The paper by Randall and Sundrum explores the implications of supersymmetry breaking in a hidden sector model, where the Standard Model particles are localized on a 3-brane in a higher-dimensional spacetime. Supersymmetry breaking occurs off the 3-brane, either in the bulk or on another 3-brane, with at least one extra dimension compactified at a scale much below the four-dimensional Planck scale. This framework offers new possibilities for solving various SUSY-related problems, such as the flavor problem, the gaugino mass problem, the CP problem, and the μ-problem. The compactification scale can also be consistent with gauge-gravitational unification. The authors demonstrate these claims using a four-dimensional effective theory that incorporates the features of the underlying higher-dimensional theory and the super-Weyl anomaly. Naturalness constraints arise from both symmetries and the higher-dimensional origins of the theory. The paper also introduces additional bulk contributions to the MSSM soft masses and discusses the predictive nature of the scenario, which is constrained by the requirement that the compactification scale is of order the GUT scale.The paper by Randall and Sundrum explores the implications of supersymmetry breaking in a hidden sector model, where the Standard Model particles are localized on a 3-brane in a higher-dimensional spacetime.
