Cosmological Collider Signatures from Right-Handed Neutrino Loop
Jingtao You, Linghao Song, Chengcheng Han +3
We study cosmological collider (CC) signatures generated by right-handed neutrino loops in the setup of inflation combined with the neutrino seesaw mechanism. We formulate the infl…
Fingerprints of a Non-Inflationary Universe from Massive Fields
Jerome Quintin, Xingang Chen, Reza Ebadi
We construct explicit models of classical primordial standard clocks in an alternative to inflation, namely the slowly contracting ekpyrotic scenario. We study the phenomenology of…
Inflation: Theory and Observations
Ana Achúcarro, Matteo Biagetti, Matteo Braglia +19
Cosmic inflation provides a window to the highest energy densities accessible in nature, far beyond those achievable in any realistic terrestrial experiment. Theoretical insights i…
