Open AccessA CFT interpretation of cosmological correlation functions in α−vacua in de-Sitter space
De-Sitter(dS) space allows for a generalized class of vacua, known as α–vacua, described by some parameters. The Bunch-Davies (BD) vacuum is a point in this parameter space. The cosmological correlation function ...

Open AccessConstraining momentum space CFT correlators with consistent position space OPE limit and the collider bound
Consistency with position space OPE limit requires three-point momentum space CFT correlators to have only total energy singularity. We show that this requirement gives a simple proof of the known result that ...
