“What if the Higgs field proves it doesn’t exist the way we think it does?”This conceptual paper explores an alternative view on fermion mass generation—not through local Yukawa couplings, but via global overlap between extended fermion wavefunctions and the Higgs field. We propose a wavefunction-based mass mechanism, outline a Hamiltonian self-overlap framework, and sketch how such an approach could explain fermion mass hierarchies without free parameters. The model aligns conceptually with extra-dimensional and composite Higgs scenarios and suggests paths toward experimental validation.
