Antihelium flux signature for antimatter globular cluster in our Galaxy

TL;DR

This paper explores the potential of the AMS experiment to detect antihelium flux signatures indicative of antimatter globular clusters in our Galaxy, testing fundamental baryosynthesis theories.

Contribution

It proposes a method to detect antimatter globular clusters via antihelium flux measurements, linking astrophysical observations with baryosynthesis models.

Findings

AMS sensitivity can test antimatter globular cluster hypotheses

Expected antihelium fluxes are calculated considering galactic interactions

Mass interval constraints for antimatter domains are established

Abstract

The AMS experiment is shown to be sensitive to test the hypothesis on the existence of antimatter globular cluster in our Galaxy. The hypothesis follows from the analysis of possible tests for the mechanisms of baryosynthesis and uses antimatter domains in the matter dominated Universe as the probe for the physics underlying the origin of the matter. The interval of masses for the antimatter in our Galaxy is fixed from below by the condition of antimatter domain survival in the matter dominated Universe and from above by the observed gamma ray flux. For this interval the expected fluxes of antihelium-3 and antihelium-4 are calculated with the account for their interaction with the matter in the Galaxy.
