关于超重磁单极子原初束缚态的丰度

On the abundance of primordial bound states of superheavy magnetic monopoles

Dmitry R. Gulevich

摘要:

有人提出,超重带电粒子可能是在宇宙暴胀结束时以原始束缚对的形式诞生的。这样的电子对被认为是超高能宇宙射线(UHECR)的来源。我们发现,原始绑定对大于$10^{-9}$厘米的磁单极子迅速热分解,由于与原始电子-正电子等离子体的相互作用,任何这样的初始原始浓度被冲洗掉。因此,最终浓度将由其平衡丰度定义。

英文摘要:

It has been suggested that superheavy charged particles might have been born in primordial bound pairs at the end of cosmic inflation. Such pairs have been proposed as a source of ultra-high energy cosmic rays (UHECR). We show that primordial bound pairs of magnetic monopoles larger than $10^{-9}$ cm quickly thermolise due to the interaction with primordial electron-positron plasma and any such initial primordial concentration is washed out. The final concentration will therefore be defined by their equilibrium abundance.
