DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CCTP_HEP/47/
 ">Decoding and bootstrapping cosmological fluctuations</a>\nby Gui Pimente
 l (Amsterdam) as part of CCTP HEP Seminars\n\n\nAbstract\nI will review ou
 r current understanding of the initial conditions of the universe\, and de
 scribe what information is available from current and future measurements 
 of cosmological correlation functions. Then I will describe a new method t
 o compute and constrain the possible shapes of those correlation functions
 \, assuming they were generated during inflation. This ``cosmological boot
 strap" draws inspiration from the modern scattering amplitudes program in 
 flat space\, as well as the conformal bootstrap of phase transitions. Afte
 r discussing primordial scalar fluctuations\, I will also explain how the 
 consistent propagation of gravitational waves imposes further constraints 
 on the structure of spinning primordial correlators.\n
