论文摘要
我们研究了f理论中u（1）量规场的无质量电荷光谱，这些光谱是由非亚伯群体破裂引起的。以这种方式出现的U（1）电荷可能非常大。特别是，使用垂直通量破裂，我们构建了一个显式的4D F理论模型，其与其他量规部门脱钩的U（1），其中无质量/光场的电荷高达657。这结果大大超过了文献中的先前结果。我们认为，heurist hearist，该结果可能会在F理论景观中的脱钩U（1）因素下为光场收费提供上限。我们还表明，当U（1）耦合到其他量规组时，电荷可能会更大。
We study the massless charged spectrum of U(1) gauge fields in F-theory that arise from flux breaking of a nonabelian group. The U(1) charges that arise in this way can be very large. In particular, using vertical flux breaking, we construct an explicit 4D F-theory model with a U(1) decoupled from other gauge sectors, in which the massless/light fields have charges as large as 657. This result greatly exceeds prior results in the literature. We argue heuristically that this result may provide an upper bound on charges for light fields under decoupled U(1) factors in the F-theory landscape. We also show that the charges can be even larger when the U(1) is coupled to other gauge groups.
