星系际磁场中的磁单极子加速

Monopole acceleration in intergalactic magnetic fields

Daniele Perri, Kyrilo Bondarenko, Michele Doro, Takeshi Kobayashi

AI总结:

该研究分析星系际磁场对磁单极子的加速作用,指出中低质量单极子可达相对论速度,并阐明其对搜寻实验、Parker bound及磁场反作用的影响。

摘要:

我们对星系际磁场中磁单极子的加速进行了全面分析。我们证明,中低质量的磁单极子可以被加速至相对论性速度。这会显著影响对磁单极子的直接和间接搜寻。作为例子,我们表明在星系际磁场存在时,Parker bound(帕克界限)会放宽。我们还发现,宇宙中的磁单极子种群可对星系际磁场产生显著的反作用。

英文摘要:

We provide a comprehensive analysis of the acceleration of magnetic monopoles in intergalactic magnetic fields. We demonstrate that monopoles with intermediate to low masses can be accelerated to relativistic velocities. This can significantly affect direct and indirect searches for magnetic monopoles. As an example, we show that the Parker bound is relaxed in the presence of intergalactic fields. We also find that a cosmic population of monopoles can produce significant backreaction on the intergalactic fields.
