Emergent gauge symmetry from Hopf soliton topology in ESFT

This preprint develops the emergence of the Standard Model gauge structure from Hopf-soliton topology in Energy String Field Theory (ESFT). The manuscript derives SU(2) weak isospin from the rotational zero modes of a single hedgehog soliton, SU(3) color from the permutation symmetry of the rank-3 Hopf-soliton sector, and U(1) from the residual outer phase field. The same framework is further connected to quantitative results including Casimir scaling, glueball-spectrum estimates, and constraints on additional gauge sectors. This version is released as a public preprint for citation and scholarly reference.
