Imprints of Spinning Particles on Primordial Cosmological Perturbations
  If there exist higher-spin particles during inflation which are light
compared to the Hubble rate, they may leave distinct statistical anisotropic
imprints on the correlators involving scalar and graviton fluctuations. We
characterise such signatures using the dS/CFT$_3$ correspondence and the
operator product expansion techniques. In particular, we obtain generic results
for the case of partially massless higher-spin states.
