Supersymmetry as an Effective Description of Moduli Geometry in Fixed-Point String Compactifications

Supersymmetry is not realized as a particle symmetry of nature and no physical superpartners are predicted at accessible energies. The algebraic structures commonly attributed to supersymmetric threshold corrections and two–Higgs–doublet parametrizations are reinterpreted as geometricnormalization effects arising from Calabi–Yau moduli. A single fixed–point selection condition on the K¨ahler volume modulus correlates three independent observables: the vacuum energy scale, the gauge coupling at the string scale through moduli–dependent thresholds, and the Higgs vacuumm expectation value ratio tan β. The Large Hadron Collider null searches are therefore expected. Geometry replaces supersymmetry as the organizing principle.
