A Holographic Mechanism for Supersymmetry Breaking and the Cosmological Constant Problem in G2 Compactifications

We present a new framework for supersymmetry breaking in string theory, grounded in holographic duality and G2 compactifications of higher-dimensional supergravity. The model naturally explains the electroweak hierarchy and generates a small positive cosmological constant without fine-tuning. A non-supersymmetric 4D Standard Model-like vacuum arises from the boundary of a higher-dimensional spacetime compactified on a topologically rich G2 manifold. We derive the effective supergravity action, moduli stabilization via fluxes, and vacuum statistics from the string landscape. Soft SUSY-breaking terms are computed from F-terms, and RG evolution is discussed. The mechanism is consistent with LHC bounds and opens a pathway toward testable UV-complete phenomenology.
