Axion Isocurvature Collider
Shiyun Lu
Cosmological colliders can preserve information from interactions at very high energy scale, and imprint them on cosmological observables. Taking the squeezed limit of cosmological…

A Cosmological Higgs Collider
Shiyun Lu, Yi Wang, Zhong-Zhi Xianyu
The quantum fluctuations of the Higgs field during inflation could be a source of primordial density perturbations through Higgs-dependent inflaton decay. By measuring primordial n…

Connections between Minkowski and Cosmological Correlation Functions
Shek Kit Chu, Mang Hei Gordon Lee, Shiyun Lu +3
We show how cosmological correlation functions of massless fields can be rewritten in terms of Minkowski correlation functions, by extracting symmetry-breaking operators from the c…
