关于镜像物质的可能观测

On the Possible Observation of Mirror Matter

Tarek Ibrahim, Pran Nath

摘要:

探讨了质量在几百GeV-TeV范围内的镜像物质存在的可能性.镜像物质很自然地出现在许多统一的粒子相互作用模型中,无论是在大统一理论中还是在弦中,通常都是以矢量的形式出现。这些矢量多重态中的一些可以逃脱获得超重质量,并保持轻到低能量,在那里它们获得电弱尺寸的矢量质量。结果发现,一个非常小的混合的矢量类多重态与MSSM物质(特别是与第三代物质)可以产生非常大的贡献的磁矩的$τ$中微子多达几个数量级,把这个时刻的范围内的可访问性改进的实验。此外,它表明,如果镜像物质存在,它会导致独特的签名在对撞机,因此这种物质可以探索在LHC能量与可用的光度。

英文摘要:

The possibility that mirror matter with masses in the several hundred GeV- TeV range exists is explored. Mirror matter appears quite naturally in many unified models of particle interactions both in GUTs and in strings often in vector-like combinations. Some of these vector-like multiplets could escape acquiring super heavy masses and remain light down to the low energies where they acquire vector-like masses of electroweak size. It is found that a very small mixing of the vector-like multiplets with MSSM matter (specifically with the third generation matter) can produce very large contributions to the magnetic moment of the $τ$ neutrino by as much as several orders of magnitude putting this moment in the range of accessibility of improved experiment. Further, it is shown that if mirror matter exists it would lead to distinctive signatures at colliders and thus such matter can be explored at the LHC energies with available luminosities.
