posted on 2023-06-12, 09:02 authored by Xavier CalmetXavier Calmet, James Edholm, Iberê KuntzIt has been shown that the spectrum of quantum gravity contains at least two new modes in addition to the massless graviton: a massive spin-0 and a massive spin-2. We calculate their power spectrum during inflation and we argue that they could leave an imprint in the cosmic microwave background should their masses be below the inflationary scale.
