6d Dirac Action的超对称性

Supersymmetry in 6d Dirac Action

Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki, Makoto Sakamoto, Kentaro Tatsumi

摘要:

本文研究了矩形面上的6d狄拉克费米子。结果表明,4d谱服从$N=2$超对称量子力学.然后,我们证明了超对称性是非常有用的分类所有允许的边界条件和扩展的卡鲁扎-克莱因模式的6d狄拉克场。该模型的一个显著特点是,即使6d狄拉克费米子具有不为零的体质量,4d质谱也可以包含简并的无质量手征费米子,这可能为解决夸克和轻子的产生问题提供了一个线索。结果表明,零能解不受边界条件的影响,而边界条件对正能解的确定有很好的作用。我们还提供了一个简短的讨论,在一般情况下,可能的边界条件,特别是那些多边形。

英文摘要:

We investigate a 6d Dirac fermion on a rectangle. It is found that the 4d spectrum is governed by $N=2$ supersymmetric quantum mechanics. Then we demonstrate that the supersymmetry is very useful for classifying all the allowed boundary conditions and to expand the 6d Dirac field in Kaluza-Klein modes. A striking feature of the model is that even though the 6d Dirac fermion has non-vanishing bulk mass, the 4d mass spectrum can contain degenerate massless chiral fermions, which may provide a hint to solve the problem of the generation of quarks and leptons. It is pointed out that zero-energy solutions are not affected by the presence of the boundaries, while the boundary conditions work well for determining the positive-energy solutions. We also provide a brief discussion on possible boundary conditions in the general case, especially those on polygons.
