Abstract:
After the recent (now defunct) results from BICEP2 on CMB B-mode polarizations, there has been considerable work on engineering a model of large field inflation. Natural inflation with axions is one class of such models and has received considerable attention. However, natural inflation models have so far strongly resisted embeddings in UV complete theories such as string theory. We argue that this is no coincidence, but rather a consequence of the weak gravity conjecture which excludes a large class of large field inflation models.
The seminar is free and open to the public. No registration is required. Seating is on a first-come first-served basis.
