On-Shell Bootstrap of Loop Inflation Correlators with Spectral Dispersion
Haoyuan Liu, Zhehan Qin, Jiayi Wu +2
We develop a new bootstrap strategy for cosmological correlators at loop level, which we call spectral dispersion. It is based on two conceptual observations that a correlator can…

Bootstrapping One-Loop Inflation Correlators with the Spectral Decomposition
Zhong-Zhi Xianyu, Hongyu Zhang
Phenomenological studies of cosmological collider physics in recent years have identified many 1-loop inflation correlators as leading channels for discovering heavy new particles…
