Anihelium flux from antimatter globular cluster

TL;DR

This paper investigates the potential existence of an antimatter globular cluster in the galactic halo by estimating the flux of helium anti-nuclei in cosmic rays and proposing a propagation model within the galaxy.

Contribution

It introduces a method to evaluate the helium anti-nuclei flux from hypothetical antimatter globular clusters and models their propagation in the galactic magnetic field.

Findings

Estimated the energy density of antiparticles in cosmic rays.

Proposed a propagation model for antinuclei in the galactic magnetic field.

Provided a framework to test antimatter cluster hypotheses.

Abstract

Macroscopic cosmic antimatter objects are predicted in baryonasymmetrical Universe in the models of strongly nonhomogeneousbaryosynthesis. We test the hypothesis of the existence of an oldglobular cluster of anti-stars in the galactic halo by evaluating theflux of helium anti-nuclei in galactic cosmic rays. Due to the symme-try of matter and antimatter we assume that the antimatter clusterevolves in a similar way as a matter cluster. The energy density ofantiparticles in galactic cosmic rays from antimatter globular clusteris estimated. We propose a method for the propagation of a fluxof antinuclei in a galactic magnetic field from the globular cluster ofantistars in the Galaxy.
