Abstract

The topological susceptibility of the electroweak sector of the Standard Model requires the existence of a pseudoscalar state η_W. It is shown that within the Standard Model, this state is not a new particle. It is identified as a CP-odd linear combination of the ground states of the hydrogen and antihydrogen atoms. Thus, η_W represents a quantum superposition of ordinary matter and antimatter, already known from atomic physics. This result links the topological properties of the vacuum with observable atomic states.

Hydrogen and its antipode — antihydrogen, discovered by Полем Дираком in 1931, annihilate each other on contact, flashing radiation. But in the quantum world, something else is possible. If two such antipodes are bound into a common structure, they don't perish but form a new object — a quantum 'vortex'.

The basis is the ability of space in the Стандартной модели to bend and form stable knots. Thanks to this, водород and antihydrogen with opposite mirror properties (like left and right) combine into one state. No new particle is needed — everything is built from ordinary atoms.

This blurs the line between particle physics and atomic physics. And the most thrilling part: such 'vortices' could be the key to the nature of dark matter — the invisible substance that governs galaxies.

🎯 Under normal conditions, hydrogen and antihydrogen instantly turn into energy. But in this state, they coexist without annihilation.

🎬 In science fiction, antimatter is explosive fuel. Yet this work suggests that antimatter can peacefully coexist with ordinary matter.
