Abstract We investigate the one loop effective potential of inflation in a standard model of chaotic inflation. The leading one loop corrections to the effective inflaton potential are evaluated in the quasi de Sitter background, and we estimate the one loop correction to the two-point function of the inflaton perturbations in the Hartree approximation. In this approximation, the one loop corrections depends on the total number of e-foldings of inflation and the maximal effect is estimated to be a correction to the power spectrum of a few percent. However, such a correction may be difficult to disentangle from the background in the simplest scenario.

- Infrared effects in inflationary correlation functions (2010, background): “A similar argument was given by Sloth, who pointed out that an observable such as the tensor fraction, r, may depend on a ratio of two quantities which receive loop corrections scaling differently as the box size increases [46, 47].”
- Semiclassical relations and IR effects in de Sitter and slow-roll space-times (2010, background): “However, it is known that already at horizon crossing the correlation functions of δφ contains IR divergences [35, 36], which cannot be captured by δN loops.”
