本文研究了在磁化轨道上紧化的10维超对称（SUSY）Yang-米尔斯理论的超对称（SUSY）模型，在额外维度中，磁场诱导了非零Fayet-Iliopoulos（FI）项.允许FI项的存在放松了基于磁化背景的超对称模型构建中对磁通配置的约束。在这种情况下，荷电场发展其真空期望值（VEV）以抵消通量规范对称性的D平坦方向上的FI项，这打破了规范对称性并导致超对称真空。基于这一思想，我们提出了一类新的具有三代夸克和轻子的超对称磁化轨道模型。特别地，我们构建了一个模型，右手sneutrinos发展的VEV恢复超对称性，但产生轻子数违反项以下的紧化标度，并显示其唯象后果。
We study supersymmetric (SUSY) models derived from the ten-dimensional SUSY Yang- Mills theory compactified on magnetized orbifolds, with nonvanishing Fayet-Iliopoulos (FI) terms induced by magnetic fluxes in extra dimensions. Allowing the presence of FI-terms relaxes a constraint on flux configurations in SUSY model building based on magnetized backgrounds. In this case, charged fields develop their vacuum expectation values (VEVs) to cancel the FI-terms in the D-flat directions of fluxed gauge symmetries, which break the gauge symmetries and lead to a SUSY vacuum. Based on this idea, we propose a new class of SUSY magnetized orbifold models with three generations of quarks and leptons. Especially, we construct a model where the right-handed sneutrinos develop their VEVs which restore the supersymmetry but yield lepton number violating terms below the compactification scale, and show their phenomenological consequences.
