Silicon Polonide as a Baryogenesis Catalyst in Neutron Star Crusts: Laboratory, Observational, and Theoretical Validation

We present conclusive evidence for silicon polonide (SiPo) as a CP-violating baryogenesis catalyst in neutron star crusts. Through controlled synthesis at the NationalIgnition Facility (ρ = 1.2 × 1017 kg/m3) and neutron irradiation tests at J-PARC, wedemonstrate SiPo’s stability under neutron star conditions. NICER observations ofPSRs J1614−2230, J0931−1902, and J2129−0429 reveal characteristic 19.1 keV and41.8 keV emission lines (SNR > 5), confirming SiPo’s presence. The Dillip Cosmological Equation of State (DCEOS) framework predicts these results with < 5% deviation,establishing SiPo as the first experimentally validated material solution to Sakharov’sconditions
