DESCRIPTION:Title: <a href="https://researchseminars.org/talk/qucos/4/">St
 udying inflationary cosmological correlators using conformal symmetry in m
 omentum space (part 2)</a>\nby Nilay Kundu (IIT Kanpur) as part of Quantum
  Cosmos Seminars\n\n\nAbstract\nDuring Inflation the universe was approxim
 ately described by deSitter (dS) space. The symmetries of a late time slic
 e of 4-dimensional dS space are the same as those of a 3-dimensional Eucli
 dean Conformal Field Theory (CFT). We will discuss how these symmetries ma
 y impose important constraints on the correlation functions of cosmologica
 l perturbations produced during inflation\, which can directly be observed
  in the CMB. Using these symmetry considerations\, we will understand the 
 Ward identities for conformal invariance\, written in momentum space\, whi
 ch imposes restrictions on those correlation functions. We will also discu
 ss how we can learn about these correlation functions computed in the alph
 a vacua of dS space by using CFT techniques in momentum space.\n
