作为暗物质的原始单极子

Primordial monopolium as dark matter

Vicente Vento

摘要:

单极子的存在是卡鲁扎-克莱因多维理论的一个特征。这些解的拓扑结构非常有趣。偶极解的存在性是本研究的主旨,偶极解的存在性与单反偶极束缚态有关。在最低能量状态下的偶极子,我们在这里也称之为单极子,在自由空间中是电磁惰性的,只与引力相互作用。当与时间相关的磁场相互作用时,单极获得时间相关的感应磁矩并辐射。我们分析了辐射单极最有利的天体物理方案,发现辐射量是如此之小,以至于不能用常规设备探测到。这些发现表明,卡鲁扎-克莱因单极子,如果存在的话,将是原始暗物质成分的候选者。

英文摘要:

The existence of monopoles is a characteristic signature of Kaluza-Klein multidimensional theories. The topology of these solutions is extremely interesting. The existence of a dipole solution, which we have associated to a monople-anti-monopole bound state, is the leitmotiv of this investigation. The dipole in its lowest energy state, which we here call also monopolium, is electromagnetically inert in free space interacting only gravitationally. Monopolium when interacting with time dependent magnetic fields acquires a time dependent induced magnetic moment and radiates. We have analyzed the most favorable astrophysical scenario for radiative monopolium and found that the amount of radiation is so small that is not detectable by conventional equipments. These findings suggest that Kaluza-Klein monopolium, if existent, would be a candidate for a primordial dark matter constituent.
