超重稳定夸克团是暗物质的可行候选者吗?

Are superheavy stable quark clusters viable candidates for the dark matter?

Norma Susana Mankoc Borstnik, Mitja Rosina

摘要:

对夸克和轻子族的起源及其性质的解释是理解标准模型假设的最有希望的方法之一。自旋-电荷-族理论确实提出了族的出现机制,并为标准模型的所有假设提供了解释,它预测了两个解耦的四族群。上面四个家族中最轻的家族有稳定的成员,它们相应地是构成暗物质的候选者。我们研究了这样一个非常重的重子被普通核子的弱散射和“核”散射(由重第五族夸克之间的色相互作用决定),以表明只要这个重子的夸克质量在100 TeV或更高,散射截面是非常小的,并且与迄今为止大多数实验中的观测结果相一致。

英文摘要:

The explanation for the origin of families of quarks and leptons and their properties is one of the most promising ways to understand the assumptions of the Standard Model. The Spin-Charge-Family theory, which does propose the mechanism for the appearance of families and offers an explanation for all the assumptions of the Standard Model, predicts two decoupled groups of four families. The lightest of the upper four families has stable members, which are correspondingly candidates to constitute the dark matter. We study the weak and the "nuclear" (determined by the colour interaction among the heavy fifth family quarks) scattering of such a very heavy baryon by ordinary nucleons in order to show that the cross-section is very small and consistent with the observation in most experiments so far, provided that the quark mass of this baryon is about 100 TeV or above.
