Theoretical modeling identifies octahedral vacuum lattice defects as dark matter candidates, predicting a 1.719 GeV particle mass and a 1.591 GeV annihilation line.
Key Points
To investigate whether octahedral interstitial voids within an FCC vacuum lattice can geometrically explain dark matter properties, mass, and annihilation signatures in the Selection-Stitch Model.
Analyzed the symmetry and bonded subgraph (complete tripartite graph K2,2,2) of octahedral voids in a K=12 FCC vacuum lattice.
Calculated structural states using a third-order closed inclusion–exclusion expansion bounded by the six vertices of the octahedron.
Applied the standing-information postulate to derive particle mass and annihilation pathways calibrated solely to proton mass without cosmological fitting.
Geometric counting yielded a structural count of C_DM = 3364, corresponding to a predicted dark matter mass of m_DM = 1.719 GeV.
Structural symmetry demonstrated that the defect is self-conjugate with no first-order electric dipole, suppressing electromagnetic coupling.
Interface geometry restricted defect annihilation to produce a gamma-ray line at E_gamma = 1.591 GeV, matching an observed 1.578 ± 0.048 GeV gamma-ray line within 0.3σ.
