我们研究了最近提出的 F 理论 GUT 模型中超对称性对风味的约束。我们将拓扑扭曲理论与八维超杨米尔斯的规范表示联系起来，并提供两者之间的字典。我们描述了有效 4 维超重力理论中超势全纯所隐含的汤川耦合的约束，包括 αGUT 的缩放。考虑到 D 项，我们由于度量和通量扰动而明确求解波函数和 Yukawa 的二阶，并找到一个没有子引导校正的一阶 Yukawa 矩阵。
We study the constraints of supersymmetry on flavour in recently proposed models of F-theory GUTs. We relate the topologically twisted theory to the canonical presentation of eight-dimensional super Yang-Mills and provide a dictionary between the two. We describe the constraints on Yukawa couplings implied by holomorphy of the superpotential in the effective 4-dimensional supergravity theory, including the scaling with αGUT. Taking D-terms into account we solve explicitly to second order for wavefunctions and Yukawas due to metric and flux perturbations and find a rank-one Yukawa matrix with no subleading corrections.
