Yukawa Couplings as Relics of the Early Universe

This paper presents Version 7 of the Oasis Framework, a phenomenological model exploring a possible cosmological origin of Yukawa couplings and fermion masses. The framework proposes that the observed mass hierarchy of elementary particles may originate from local electroweak conditions that existed during the early Universe. Rather than treating Yukawa couplings as fundamental numerical constants, the model investigates whether they could emerge from physical processes associated with different electroweak environments. Version 7.1 introduces several major developments, including a thermalization-based mechanism for the formation of homogeneous regions, the distinction between free and bound dressing, and a refined description of how local electroweak conditions may become encoded into effective particle properties. The work also examines several possible dressing mechanisms and identifies condensate-based gap-equation dressing as the most promising candidate for the generation and stabilization of residual electroweak dressing. In addition, the framework is connected to established concepts from modern physics, including electroweak crossover dynamics, quantum field theory dressing, dynamical mass generation, gap equations, inhomogeneous condensates, and quantum chromodynamics. The resulting picture suggests that the fermion mass hierarchy may reflect different electroweak histories experienced during the early Universe, providing a new phenomenological perspective on the flavour problem. This work is intended as an exploratory theoretical framework and a foundation for future mathematical development.
