Scalar one-loop tensor power spectrum during single-field inflation (2410.16688v2)
Published 22 Oct 2024 in astro-ph.CO, gr-qc, hep-ph, and hep-th
Abstract: We calculate the scalar-induced one-loop correction to the power spectrum of tensor perturbations produced during single-field slow-roll inflation. We find that the correction is given by the square of the product of the slow-roll parameter and the tree-level scalar power spectrum. We also discuss the implications of the logarithmic contribution.
