Beyond perturbation theory in inflation

Download to your calendar using vCal

If you have a question about this talk, please contact Dr Dong-Gang Wang .

Deviations from Gaussianity in inflation are usually calculated using perturbation theory. This method, however, fails for unlikely events on the tail of the probability distribution, like the formation of a primordial black hole. I explain how one can explore these unlikely events using semiclassical methods and then discuss the case of resonant non-Gaussianity.
