Cosmological matter-antimatter asymmetry as a quantum fluctuation
Archil Kobakhidze, Adrian Manning
TL;DR
This paper proposes a novel idea that the universe's matter-antimatter imbalance originated from quantum fluctuations during cosmic inflation, challenging traditional baryogenesis theories.
Contribution
It introduces a new paradigm where matter-antimatter asymmetry results from quantum fluctuations in the early universe, differing from existing mechanisms.
Findings
Suggests quantum fluctuations can produce observed asymmetry
Provides a new framework for matter-antimatter imbalance
Links inflationary physics to baryon asymmetry
Abstract
We entertain a new paradigm according to which the observed matter-antimatter asymmetry is generated as a large-scale quantum fluctuation over the baryon-symmetric state that occurred during the cosmic inflation.
