Two Kinds of Antimatter

Before proceeding, a crucial distinction. Antimatter is observed in the laboratory. Positrons appear in PET scans. Antiprotons are produced at CERN. Antimatter exists in the visible universe. This is not in dispute.

The axioms account for this. Local antimatter arises through pair production — the break creating paired elements (σ-images) that exist briefly on the manifold before annihilating. This is the standard QFT process.

It operates entirely within the ℒ-sector and does not require the σ-boundary to be crossed.

The baryogenesis problem is not about local pair production. It is about the net asymmetry: why, after all annihilation is complete, does a surplus of matter remain in the visible universe?

Where is the missing antimatter?

The answer: it is inside the event horizons.
