| Abstract: |
The BICEP2 experiment has been specifically designed to search for the signal of inflationary gravitational waves in the B-mode polarization of the cosmic microwave background (CMB). The results reported by the experiment are perfectly consistent with the detection of a large excess in the B-mode spectrum in exactly the range where an inflationary gravitational wave signal is expected to peak. This potentially provides us with a crucial piece of observational evidence for inflation that has been long sought.
In this talk, I describe generation of the gravity waves during inflation and their effect on the CMB polarization. Then I discuss implications of the BICEP 2 results for models of inflation, in particular how it can pin down the energy scale of inflation. |
