6D超引力理论中U(1)电荷谱的无限沼泽区

An infinite swampland of U(1) charge spectra in 6D supergravity theories

Washington Taylor, Andrew P. Turner

摘要:

本文分析了单阿贝尔U(1)规范因子对6D超引力理论的异常约束。对于电荷限制在$q = \pm1, \pm2$且没有张量多重态的理论,无异常模型几乎完美地匹配那些可以从F理论紧化实现的模型。对于具有张量多重态或具有较大电荷的理论,F理论的约束不太容易理解。然而,我们发现,有一个无限类的不同的无质量的电荷谱的“沼泽地”的理论,满足所有已知的量子一致性条件,但不承认实现通过F-理论或任何其他已知的方法弦紧化。我们还比较了阿贝尔理论中带电物质的谱与非阿贝尔SU(2)和高阶规范对称性破缺所能实现的谱。

英文摘要:

We analyze the anomaly constraints on 6D supergravity theories with a single abelian U(1) gauge factor. For theories with charges restricted to $q = \pm1, \pm2$ and no tensor multiplets, anomaly-free models match those models that can be realized from F-theory compactifications almost perfectly. For theories with tensor multiplets or with larger charges, the F-theory constraints are less well understood. We show, however, that there is an infinite class of distinct massless charge spectra in the "swampland" of theories that satisfy all known quantum consistency conditions but do not admit a realization through F-theory or any other known approach to string compactification. We also compare the spectra of charged matter in abelian theories with those that can be realized from breaking nonabelian SU(2) and higher rank gauge symmetries.
