Carrollian bosonic supergravity at order α' and the universal cancellation of higher-curvature divergences
Abstract
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, Riem1 ⋯ RiemN, 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.

AB - 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, Riem_1 ⋯ 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.
