Highly suppressed detection probability of the primordial antimatter in the present-day universe

High Energy Physics - Phenomenology 2026-04-06 v1

Abstract

We show that the matter-antimatter asymmetry in the present-day universe is mainly due to the highly suppressed detection probability for the primordial antimatter, which is a direct result of the Dirac-Feynman-Stueckelberg interpretation of antimatter and the extremely time asymmetric expansion of the primordial universe.
