DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EASW/11/">Th
 e Cosmological Bootstrap</a>\nby Daniel Baumann (Univ. of Amsterdam) as pa
 rt of East Asian String Webinars\n\n\nAbstract\nThe past decade has seen a
 n explosion of progress in our understanding of scattering amplitudes in g
 auge theory and gravity. New bootstrap methods have revealed hidden symmet
 ries and new mathematical structures that are completely invisible in the 
 standard approach of Lagrangians and Feynman diagrams. Inspired by these d
 evelopments\, the bootstrap philosophy has recently been applied to cosmol
 ogy. In this talk\, I will describe our work on the bootstrapping of cosmo
 logical correlations. \n\nThe talk will have two parts: In the first part\
 , I will describe the conceptual foundations of the "cosmological bootstra
 p” as developed together with Arkani-Hamed\, Lee and Pimentel in [arXiv:
 1811.00024]. In the second part\, I will describe the extension of these i
 deas to massless particles with spin\, where locality provides important n
 ew constraints. This is work to appear with Duaso Pueyo\, Joyce\, Lee and 
 Pimentel.\n
