Massive scalar's self-mass from gravitons in de Sitter

Year: 2026

Type: preprint

Abstract: We compute the fully renormalized one-graviton-loop contribution to the self-mass of a massive scalar field in de Sitter space. The computation is performed using dimensional regularization and the divergences are absorbed by BPHZ counterterms. This self-mass can be used to study one-loop quantum-gravitational corrections to the dynamics of massive spectator scalars in inflation.
