SUSY Rilles: A Speculation on Superstring Signatures in the Cosmic Microwave Background

portrait of Gates
Virtual Meeting

We speculate about the imprint of higher spin supermultiplets on cosmological correlators, i.e., the non- Gaussianity of the cosmic microwave background. Supersymmetry is used as a guide to introduce the contribution of fermionic higher spin particles, which have been neglected thus far in the literature. We compute the curvature perturbation 3-point function for supersymmetric higher-spin particle exchanges and find the known P(cos) angular dependence is accompanied by superpartner contributions.
