Searching for Cosmological Collider in the Planck CMB Data

Sohn, Wuhyun, Wang, Dong-Gang, Fergusson, James R. et al.

Understand

In this paper, we present the first comprehensive CMB data analysis of cosmological collider physics.

New heavy particles during inflation can leave imprints in the primordial correlators which are observable in today's cosmological surveys.
This remarkable detection channel provides an unsurpassed opportunity to probe new physics at extremely high energies.
Here we initiate the search for these relic signals in the cosmic microwave background (CMB) data from the Planck legacy release.
