关于磁性物质

On the magnetic monopole mass

Vicente Vento, Valentina Sarti Mantovani

摘要:

自从狄拉克建立了磁单极子的存在与电荷量子化之间的关系以来,磁单极子一直是人们感兴趣的课题。特胡夫特和波利亚科夫证明,他们可以产生于规范理论的结果,一个非平凡的拓扑结构。在他们的方案中,介子的质量与统一尺度下对称性自发破缺所产生的矢量介子质量成正比。为了从大统一模型尺度减少到标准模型尺度,我们根据科尔曼-温伯格方案修改了势,并产生了第二个更深的最小值,使原来的真空量子力学不稳定。这种机制导致了较低质量的辐射单极子,可以在LHC上检测到。

英文摘要:

Magnetic monopoles have been a subject of interest since Dirac established the relation between the existence of a monopole and charge quantization. 't Hooft and Polyakov proved that they can arise from gauge theories as the result of a non trivial topology. In their scheme the mass of the monopole turns out to be large proportional to the vector meson mass arising from the spontaneous breaking of the symmetry at unification scales. To reduce from the GUT scale to the Standard Model scale we modify the potential in line with Coleman-Weinberg schemes and generate a second deeper minimum turning the original vacuum quantum mechanically unstable. This mechanism leads to radiating monopoles of lower mass which could be detected at LHC.
