论文摘要
我们得出了一种新的软定理，该定理对应于Lorentz提升的自发断裂。这是由于次马（扁平空间）极限的通胀动力学的动力，在该限制中，时空变得平坦，但Lorentz的提升仍然被损坏。在此极限下，散射幅度变得明智。我们将金石玻色子的软发射与硬散射幅度的（非偏见）洛伦兹的增强联系起来。这是Lorentz增强剂自发断裂的壳化身，类似于手性对称性破裂中乳腺的Adler零。我们对通货膨胀的多种应用发表评论，包括证明迪拉克出生的侵袭性通货膨胀是一种独特的理论，当增强物被自发破坏时，它具有新兴的洛伦兹的不变性。
We derive a new soft theorem that corresponds to the spontaneous breaking of Lorentz boosts. This is motivated by the dynamics of inflation in the sub-horizon (flat-space) limit, where spacetime becomes flat but Lorentz boosts are still broken. In this limit, the scattering amplitudes become sensible observables. We relate the soft emission of a Goldstone boson to the (non-relativistic) Lorentz boost of the hard scattering amplitudes. This is the on-shell avatar of the spontaneous breaking of Lorentz boosts, analogous to the Adler zero of pions in the chiral symmetry breaking. We comment on several applications to inflation, including the demonstration that Dirac-Born-Infeld Inflation is the unique theory that has an emergent Lorentz invariance when the boosts are spontaneously broken.
