Interferential Selection as a Dynamical Origin of Phase Orientation and Quantum Probabilities

This work introduces interferential selection as a general dynamical mechanism through which continuous quantum phase degrees of freedom give rise to robust, sign-like observables and stable probabilistic structures. Without modifying the formalism of quantum theory, invoking wavefunction collapse, or introducing hidden variables, the analysis shows how linear superposition and time evolution statistically enhance phase-coherent configurations while suppressing incoherent ones through self-averaging interference. The framework explains how phase orientation emerges as a dynamically stabilized relational property, shaping probability landscapes prior to realization. This mechanism provides a unified interpretation of several apparently distinct phenomena, including the emergence of Born-rule statistics in continuous quantum measurement and the appearance of extended, sign-coherent CP-asymmetry domains in multibody hadron decays. Using model-independent analyses of publicly available experimental data, the work demonstrates that CP-asymmetry sign coherence in three-body B-meson decays is robust against magnitude randomization and persists even below conventional asymmetry thresholds. The same sign-coherence methodology is applied to neutrino oscillation data (STEREO experiment), classical turbulence, and condensed-matter STM measurements, revealing a consistent hierarchy in which orientation stabilizes prior to amplitude across disparate interferential systems. Interferential selection thus emerges as a domain-independent organizing principle, clarifying how phase information becomes physically relevant through dynamical stability under interference, while remaining fully compatible with standard quantum mechanics and quantum field theory.
