我们强化了具有U(1)对称性的f理论大统一理论中与超电荷通量相关的约束,并认为它们是由于四维异常抵消而产生的。这为在光谱覆盖模型中观察到的所有限制提供了物理解释,同时证明了一组动机良好的模型的现象学含义与任何特定的形式主义无关。
We sharpen constraints related to hypercharge flux in F-theory grand unified theories that possess U(1) symmetries and argue that they arise as a consequence of four-dimensional anomaly cancellation. This gives a physical explanation for all restrictions that were observed in spectral cover models while demonstrating that the phenomenological implications for a well-motivated set of models are not tied to any particular formalism.
