质量维为1的费米子场与O'Raifeartaigh模型的耦合

Coupling of fermionic fields with mass dimensions one to the O'Raifeartaigh model

Kai E. Wunderle, Rainer Dick

摘要:

本文的目的是讨论质量维为1的费米子场与O'Raifeartaigh模型的耦合,以研究质量维为1的费米子场的超对称破缺。我们发现,耦合模型有两个不同的解决方案。第一个解决方案代表了一个局部极小的超势自发打破超对称性完美的类比O'Raifeartaigh模型。第二个解更有趣,因为它对应于超势的全局最小值。在这种情况下,与费米扇区的耦合恢复了超对称性。然而,这是以破坏洛伦兹不变性为代价的。最后给出了耦合模型多重态的质量矩阵。它包含两个玻色子三重态和一个费米子二重态,它们是质量多重态。此外,它包含一个无质量的费米子二重态以及一个费米子三重态,这不是一个质量多重态,而是一个相互作用多重态,包含不同质量维度的分量场。这些结果表明,提出的模型与质量维1的费米子场是一个可行的候选人超对称暗物质,可以在不久的将来访问的实验。

英文摘要:

The objective of this article is to discuss the coupling of fermionic fields with mass dimension one to the O'Raifeartaigh model to study supersymmetry breaking for fermionic fields with mass dimension one. We find that the coupled model has two distinct solutions. The first solution represents a local minimum of the superpotential which spontaneously breaks supersymmetry in perfect analogy to the O'Raifeartaigh model. The second solution is more intriguing as it corresponds to a global minimum of the superpotential. In this case the coupling to the fermionic sector restores supersymmetry. However, this is achieved at the cost of breaking Lorentz invariance. Finally, the mass matrices for the multiplets of the coupled model are presented. It turns out that it contains two bosonic triplets and one fermionic doublet which are mass multiplets. In addition it contains a massless fermionic doublet as well as one fermionic triplet which is not a mass multiplet but rather an interaction multiplet that contains component fields of different mass dimension. These results show that the presented model for fermionic fields with mass dimension one is a viable candidate for supersymmetric dark matter that could be accessible to experiments in the near future.
