M-理论中的超对称破缺、模稳定化和U(1)隐破缺

Supersymmetry Breaking, Moduli Stabilization and Hidden U(1) Breaking in M-Theory

Bobby Samir Acharya, Mahdi Torabian

摘要:

本文计算和研究了G_2流形上紧化M理论的模势,其中超势由一个膜瞬子项和一个渐近自由的隐扇形规范相互作用项所支配.我们表明,所有的模量可以稳定和隐藏的部门规范对称性可以在高尺度Higgsed。然后,我们计算的超伙伴质量的光谱在大统一体尺度和发展它的电弱尺度。我们发现了一个光谱,这是非常相似的G_2-MSSM与轻gauginos -在大型强子对撞机访问-和中性wino暗物质的候选人。

英文摘要:

We calculate and explore the moduli potential for M-Theory compactified on G_2-manifolds in which the superpotential is dominated by a single membrane instanton term plus one from an asymptotically free hidden sector gauge interaction. We show that all moduli can be stabilized and that hidden sector gauge symmetries can be Higgsed at a high scale. We then compute the spectrum of superpartner masses at the GUT scale and evolve it to the electroweak scale. We find a spectrum which is very similar to the G_2-MSSM with light gauginos - accessible at the LHC - and a neutral wino dark matter candidate.
