SUMMARY:Non-Gaussianity as a Particle Detector - Hayden Lee (University of
  Cambridge)
DTSTART:20161010T120000Z
DTEND:20161010T130000Z
UID:TALK67650@talks.cam.ac.uk
CONTACT:Tobias Baldauf
DESCRIPTION:Cosmological correlation functions encode the spectrum of part
 icles during inflation\, in analogy to scattering amplitudes in colliders.
  In this talk\, I will discuss the imprints of massive particles with spin
  on cosmological correlators. The spinning case is particularly interestin
 g because the detection of massive higher-spin particles would be indicati
 ve of a stringy origin of inflation. I will describe their key spectroscop
 ic features in the scalar and tensor bispectra\, and discuss scenarios in 
 which they lead to observable non-Gaussianity.
