论文摘要
最近，Kim，Shiu和Vafa提出了六个维度超级理论的一般一致性条件，从耦合到字符串的超级超对称性最小。我们在显式扰动的方向模型中测试它们，以揭示这些约束的显微镜起源。基于扰动数据，我们猜想了任何六维理论的零电荷的存在$ q \ cdot q = 0 $，具有至少一个张量多重的，与电荷$ q $的字符串缺陷耦合。然后，我们包括新的约束，以排除一些目前尚无字符串或F理论实现的六维超对称异常示例。我们还研究了从tachyon noven Free Vacua中损坏超对称性的情况下，从耦合到字符串缺陷的约束，其中包含Brane Supersymmetry Breaking类型的非BPS构型，其中断裂位于抗邻苯二醇中。在这种情况下，每当弦缺损经历超对称性破裂时，某些条件自然会更改或放松，而如果约束与超对称性断裂源分离，则约束仍然有效。
Recently, Kim, Shiu and Vafa proposed general consistency conditions for six dimensional supergravity theories with minimal supersymmetry coming from couplings to strings. We test them in explicit perturbative orientifold models in order to unravel the microscopic origin of these constraints. Based on the perturbative data, we conjecture the existence of null charges $Q \cdot Q=0 $ for any six-dimensional theory with at least one tensor multiplet, coupling to string defects of charge $Q$. We then include the new constraint to exclude some six-dimensional supersymmetric anomaly-free examples that have currently no string or F-theory realization. We also investigate the constraints from the couplings to string defects in case where supersymmetry is broken in tachyon free vacua, containing non-BPS configurations of brane supersymmetry breaking type, where the breaking is localized on antibranes. In this case, some conditions have naturally to be changed or relaxed whenever the string defects experience supersymmetry breaking, whereas the constraints are still valid if they are geometrically separated from the supersymmetry breaking source.
