Description:
Author(s): Azadeh Moradinezhad Dizgah, Gabriele Franciolini, Alex Kehagias, and Antonio Riotto The presence of massive particles with spin during inflation induces distinct signatures on correlation functions of primordial curvature fluctuations. In particular, the bispectrum of primordial perturbations obtains an angular dependence determined by the spin of the particle, which can be used to... [Phys. Rev.
