拓扑暗物质

Topological Dark Matter

Hitoshi Murayama, Jing Shu

摘要:

Kibble机制大大低估了拓扑缺陷的产生,最近在原子和凝聚态系统中证实了这一点。如果非热产生,它们可能是质量为1-10 PeV的宇宙学暗物质。如果被热化,质量为1-10 TeV的Skyrmion也是一个可行的暗物质候选者,其衰变可以解释PAMELA、FERMI和HESS最近测量的宇宙射线中的$e^\pm$光谱。产生低于暴胀尺度的磁单极子的模型,如Pati-Salam统一,被排除在外。

英文摘要:

Kibble mechanism drastically underestimates the production of topological defects, as confirmed recently in atomic and condensed matter systems. If non-thermally produced, they can be cosmological dark matter of mass 1-10 PeV. If thermalized, skyrmion of mass 1-10 TeV is also a viable dark matter candidate, whose decay may explain $e^\pm$ spectra in cosmic rays recently measured by PAMELA, FERMI, and HESS. Models that produce magnetic monopoles below the inflation scale, such as Pati-Salam unification, are excluded.
