Paper 52: Emergent Pions and Nuclear Binding from Holosphere Shell Interactions: A Structural Approach to QCD

This paper presents a structural reinterpretation of nuclear binding and pion mediation within Holosphere Theory. Instead of treating pions as fundamental quark–antiquark particles exchanged between nucleons, we model pion-like mediators as transient coherence–strain bridges that form between adjacent Holospheres in a discrete rotational lattice. In this framework, nuclear binding energy arises from the angular strain required to maintain triadic rotational compatibility across interface shells. We introduce a compact effective strain-bridge energy model in which the characteristic mediator scale and interaction range are governed by mismatch amplitude, lattice stiffness, and coherence attenuation length. The exponential falloff of the interaction emerges from coherence loss under repeated interface transfer rather than from particle mass propagation alone. Calibration at the pion scale (~140 MeV) is shown to be consistent within an effective-model regime. The approach naturally accounts for short-range attraction and saturation via finite coherence capacity. Several measurement targets are identified, including environment-dependent shifts in effective mediator parameters and possible orientation-sensitive binding signatures. The model is presented as a lattice-mechanical alternative description of short-range nuclear attraction, formulated at the level of declared coherence observables rather than gauge-field primitives.
