                    "Effective Field Theory in Inflation"



Kivonatos ismertetés:
Although the observed CMB is at very low energy, it encodes ultra high-energy 
physics in spatial variations of the photon temperature and polarization 
fluctuations. This effect is believed to be dominated by the initial quantum 
state of the Universe. I will describe the first theoretical tools by which 
to construct such a state from fundamental physics. One can then use this 
technique to reliably calculate corrections to the power spectrum, 
non-Gaussianity, etc from high-energy physics. We may soon be able to compare 
these predictions against experiment, allowing one to rule out classes of 
quantum gravity models. Now is the critical time to undertake such 
investigations, with a number of ongoing and planned experiments such as 
Planck and CMBPol/Inflation Probe poised to collect a wealth of precision data.
