Title: On loops in inflation: Can these corrections become large?
Abstract:
In next Monday I would like to talk about loop corrections to the curvature perturbation
in the single-field inflation paradigm, where we intend to draw a new perspective to
Weinberg's question: "Can loop corrections become large?" [hep-th/0605244].
I will introduce a special in-in formalism to show that the loop-contribution may be more
important than the previous conclusion due to the transition of vacuum expectation
values of spectator fields during inflation.
