[[UTAPwiki/セミナー/初期宇宙・相対論速報]] Speaker: Yi-Peng Wu (RESCEU) 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. &br; |
