Abstract
In this talk I review a recently proposed modulation of the power spectrum of primordial density fluctuations generated through transplankian (maybe stringy) effects during inflation. I briefly discuss the mechanism leading to the modulation, apply it to a generic slow-roll scenario of inflation and argue that the effects obtained are rather generic signatures of transplanckian physics. I also investigate how these primordial modulation effects may leave an imprint in the cosmic microwave background radiation, possibly detectable by satellite experiments.KeywordsCosmic Microwave BackgroundPlanck ScaleHubble ConstantLoop AmplitudeString ScaleThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
