Inherited Cosmic Neutrino Background within the HRDCC Framework
Abstract
The origin, physical nature, and cosmological role of the Cosmic Neutrino Background (CNB) remain central open questions in modern cosmology. Within the standard cosmological model, relic neutrinos are regarded as a natural consequence of thermal decoupling in the early Universe and are expected to contribute to the radiation and matter sectors throughout cosmic evolution. However, the possible role of inherited neutrino populations across successive cosmological cycles has received comparatively little attention. Within the effective phenomenological framework introduced in Paper I of the HRDCC publication program, and following the interpretation of the effective cold-dark-matter sector developed in Paper II, the present work investigates the inherited cosmic neutrino sector as a natural extension of the framework. The inherited neutrino population is introduced phenomenologically through the regularized Holographic Transition Core (HTC), where effective physical degrees of freedom may persist across successive cosmological cycles without specifying the underlying microscopic transfer mechanism. The proposed interpretation suggests that the inherited neutrino sector may contribute to the effective warm-dark-matter component while simultaneously participating in entropy regulation during cosmological transitions. Within this effective description, the Pauli exclusion principle, the Bekenstein entropy bound, and the phenomenological Neutrino Valve are interpreted as complementary elements of a common thermodynamic picture. Their combined action provides a qualitatively consistent mechanism for entropy transfer across successive cosmological cycles while preserving the deliberate separation between the effective phenomenological framework and its possible microscopic interpretation. The present paper intentionally remains at the effective phenomenological level. No detailed microscopic neutrino transport model, quantum-gravitational derivation, or particle-physics realization is assumed. Instead, the work establishes a logically consistent interpretation that connects the inherited cosmic neutrino background with effective warm-dark-matter phenomenology, entropy regulation, and long-term cyclic cosmological evolution. Detailed microscopic mechanisms are deferred to subsequent investigations. This manuscript constitutes the first paper of the HRDCC publication program. It is distributed as a preprint and has not undergone formal peer review.
