Sensing the Inflationary Production of Scalars
A. J. Foraci, C. Litos, R. P. Woodard
We review the mechanism by which loops of matter fields contribute to the graviton self-energy during de Sitter inflation. The self-energy is used to quantum-correct the linearized…

Resumming Fermion Loops for Inflationary Gravity
A. J. Foraci, R. P. Woodard
We compute the 1-loop contribution to the graviton self-energy from a loop of massless fermions on a general cosmological background. The result is used to quantum-correct the line…

Resumming Photon Loops for Inflationary Gravity
A. J. Foraci, R. P. Woodard
A previous calculation of the 1-loop photon contribution to the graviton self-energy on de Sitter background is considered. We first show that there is no local obstacle to conserv…
