Xennon and Anti-Xennon: A Spinor-Phase / Dark-Compound Framework for a Model-Based Dark-Sector Pair

Abstract

This work develops a dual interpretation of a dark-sector structure named Xennon and its conjugated partner Anti-Xennon. The first branch is a spinor-phase and charge-conjugation construction in which a positive-frequency state, Q_D(t)=exp(+iω_D t)ψ_D, is paired with a negative-frequency conjugated state, Q_Dbar(t)=exp(−iω_D t)ψ_D^c. The second branch is a non-particle dark-compound interpretation in which dark-sector structure is not assumed to be built from discrete particles, but from field-gradient resonance, described by ρ_dark compound = d_e / |∇E|. The manuscript connects these two branches through a quasi-particle/emergent-resonance interpretation: Xennon may be described either as a weakly interacting scalar/Higgs-portal dark-sector particle or as a stable resonance node of a dark compound field. The external data alignment uses the supplementary likelihood dataset of Balan et al. for AMS-02 antiproton constraints in global dark matter fits. From the processed dataset, the highest compatibility region is centered at m_D ≈ 61.66 GeV/c², equivalent to approximately 1.10 × 10^−25 kg. The selected point has λ_hS ≈ 1.36 × 10^−3, <σv> ≈ 2.87 × 10^−28, Ωh² ≈ 1.07 × 10^−2, σ_SI,p ≈ 4.25 × 10^−48 cm², and σ_SI,n ≈ 4.45 × 10^−48 cm². These values suggest an extremely weakly interacting, likely neutral or hidden-charge dark-sector structure. The work is framed as a model-based identification of a conjugated pair, not as an absolute proof or direct detector discovery.
