Abstract：If there are new particles coupled to the inflaton field, unusual signatures in the distribution of galaxies can appear. This is partly because galaxies do not trace the mass density linearly. This provides a unique opportunity to search for new particles that particle colliders on the earth can never achieve in the near future. In the talk, I will review how this idea works based on simple models.
