입자이론연구실에서 Cambridge UniversityHayden Lee 박사님을 초청하여 아래와 같이 세미나를 개최합니다.

학과 구성원 여러분의 많은 참석을 부탁드립니다.



○ 일시: 2017년 8월 21일(월) 오전 10:30

○ 장소: 제1과학관 기초과학연구소세미나실(31317호)

○ 연사: Dr. Hayden Lee  (Cambridge University)

○ Title: Non-Gaussianity as a Particle Detector



○ Abstract:   Cosmological correlation functions encode the spectrum of particles during inflation, in analogy to scattering amplitudes in colliders. In this talk, I will discuss the imprints of massive particles with arbitrary spin on cosmological correlators. The spinning case is particularly interesting because the detection of massive higher-spin particles would be indicative of a stringy origin of inflation. I will describe their key spectroscopic features in the scalar and tensor bispectra, and discuss scenarios in which they lead to observable non-Gaussianity.
