双场论中的立方Action

Cubic Action in Double Field Theory

Chen-Te Ma

摘要:

我们利用双场论研究了环面上$N_L+N_R=2$态的靶空间理论。当所有的空间维度都是非紧的时,自旋为2的Fierz-Pauli场是不允许的。在靶空间理论中,质量态提供了非零动量和缠绕数。为了导出立方作用,我们提供了唯一的约束$N_L\neq N_R$兼容的集成部分。我们首先把有质量场和无质量场对应起来。通过引入质量项,二次作用量是规范不变的。然后我们继续进行立方顺序。通过引入一型场与其他场的耦合,立方作用量也是规范不变的。大质量态不遵循一致截断。人们应该期待通过对无限模式求和的自洽理论。因此,朴素的期望在三次方阶上都是错误的。最后,我们证明了动量模和缠绕模不能同时出现在一个紧致的双空间中。

英文摘要:

We study target space theory on a torus for the states with $N_L+N_R=2$ through Double Field Theory. The spin-two Fierz-Pauli fields are not allowed when all spatial dimensions are non-compact. The massive states provide both non-vanishing momentum and winding numbers in the target space theory. To derive the cubic action, we provide the unique constraint for $N_L\neq N_R$ compatible with the integration by part. We first make a correspondence of massive and massless fields. The quadratic action is gauge invariant by introducing the mass term. We then proceed to the cubic order. The cubic action is also gauge invariant by introducing the coupling between the one-form field and other fields. The massive states do not follow the consistent truncation. One should expect the self-consistent theory by summing over infinite modes. Hence the naive expectation is wrong up to the cubic order. In the end, we show that the momentum and winding modes cannot both appear for only one compact doubled space.
