Zhong-Zhi Xianyu, Harvard University, "Standard Model Background of the Cosmological Collider"
KICP seminar: Feb 24 @ 12 PM, ERC 401
Primordial non-Gaussianities record interactions of fields in the early universe, which can be viewed as collision events in a "Cosmological Collider" with huge energy. In this talk, I shall introduce the workings of the Cosmological Collider as an explorer of new physics at very high scales, and describe the Standard Model spectrum during inflation and its "background signals" in Cosmological Collider.
