Title: Some issues on cosmic loop corrections
Date: Mon, Dec. 17th, 2012, 14:00 - 16:00
Location: 1st floor at the 4th Bldg of Science faculty
Abstract:
I will first briefly review the status of loop corrections in cosmology.
Then a few open questions are discussed (but not answered):
(1) The vacuum selection problem at the non-linear level
(2) The UV divergence and unitarity problem of time dependent EFT
(3) The IR challenges: The growth, resummation and divergence
