研究玻色子超引力的卡罗尔极限，通过纳入α'修正项证明其保持有限，构建有效作用量。建立通用标准确定高曲率贡献的有限性，应用此标准证明α'²和α'³修正的卡罗尔极限有限并推导其对作用量的贡献。
AI 中文摘要
我们证明，在纳入α'修正产生的四阶导数项后，玻色子超引力的卡罗尔极限保持有限，并明确构建了有效作用量。我们还建立了一个通用标准，以确定由黎曼张量幂次Riem₁⋯Riemₙ（n>1）给出的高曲率贡献的有限性。作为该标准的应用，我们证明了纯引力α'²和α'³修正具有有限的卡罗尔极限，推导了它们对作用量的明确贡献，并表明与ζ(3)成比例的项在α'³阶对卡罗尔型玻色子超引力无贡献。
英文摘要
We prove that the Carrollian limit of bosonic supergravity remains finite after including the four-derivative terms arising from the $α'$-corrections, and we explicitly construct the effective action. We also establish a universal criterion to determine the finiteness of higher-curvature contributions given by powers of the Riemann tensor, ${\rm Riem}_1 \cdots {\rm Riem}_N$, with $N>1$. As applications of this criterion, we prove that the purely gravitational $α'^2$- and $α'^3$-corrections admit a finite Carrollian limit, derive their explicit contributions to the action, and show that the terms proportional to $ζ(3)$ do not contribute to the Carrollian bosonic supergravity at order $α'^3$.
