SUMMARY:Decoding the Dark Universe: From the Big Bang to Large Scales
DESCRIPTION:Featuring Rafael Porto\, ICTP\n\nPart of the HET Seminar Series
	.\n\nAbstract:\nIn spite of the recent remarkable achievements in observati
	onal cosmology\, several questions about the primordial seed of structure r
	emain open. Perhaps the most outstanding one is whether the canonical frame
	work involving a (weakly coupled) fundamental scalar field played the role 
	of the `Higgs mechanism' in the early universe\, or if the anisotropies we 
	observe today have a different origin within the inflationary paradigm. Aft
	er introducing the bottom up\, or effective field theory (EFT)\, approach t
	o the dynamics of the early universe\, I will discuss the existence of theo
	retical thresholds that become natural observational targets to test physic
	s beyond the canonical framework. Then\, I will describe what we may learn 
	about inflation from future experiments\, and overview an ongoing program (
	based on using EFT methods to produce accurate analytic predictions on larg
	e scales) to approach these thresholds using data from large scale structur
	e (LSS) surveys. Concluding\, I will briefly describe how the EFT approach 
	to LSS may also allow us to constrain models of dark energy and dark matter
	.
