论文摘要
超级$α$ attractor通货膨胀模型的简单性的关键是Volkov-Akulov Fermions，通常是以Nilpotent Superfield的形式。在这里，我们探讨了使用双拷贝来构建与超级重力结合的狄拉克出生式塞菲尔德 - 沃尔科夫 - 阿库洛夫（DBIVA）理论的可能性。颜色对偶的引导程序在通过质量尺寸的订单中通过五点树级别的顺序接收散射幅度，但需要引入$ \ text {tr}（f^3）$ operator。最近发现，与该操作员的仪表理论要求高衍生的操作员塔与颜色界面二元性兼容。最保守的伴奏型双拷贝结构似乎需要DBIVA + PUREPOINCARé超级散射幅度的紫外线完成，以涉及涉及与Weyl-Inerstein超级重度的DBIVA样颗粒的一系列理论。我们还指出了颜色偶数计式乳头的替代解决方案，该解决方案允许伴随双拷贝，而无需较高衍生校正的塔，但以标量之间的交换对称为代价。
Key to the simplicity of supergravity $α$-attractor models of inflation are Volkov-Akulov fermions, often in the form of nilpotent superfields. Here we explore the possibility of using the double-copy to construct theories of Dirac-Born-Infeld-Volkov-Akulov (DBIVA) coupled to supergravity. A color-dual bootstrap admits scattering amplitudes involving pions and vectors through five-point tree-level order by order in mass-dimension, but requires the introduction of a $\text{Tr}(F^3)$ operator. Gauge theories with this operator were recently found to require a tower of higher-derivative operators to be compatible with color-kinematics duality. Adjoint-type double-copy construction at its most conservative seems to require the UV completion of DBIVA + pure Poincaré supergravity scattering amplitudes to a family of theories involving DBIVA-like particles coupled to Weyl-Einstein supergravity. We also point out an alternative solution to color-dual gauged pions that allows adjoint double-copy without a tower of higher derivative corrections but at the cost of exchange symmetry between scalars.
