Massive 3D Gravity Big-Bounce

Abstract

The properties of an extension of the New Massive 3D Gravity by scalar matter with Higgs-like self-interaction are investigated. Its perturbative unitarity consistency is verified for a family of cosmological Bounce solutions found by the superpotential method. They correspond to the lower bound $\lambda =-1$ of the BHT unitarity window and describe eternally accelerated 3D Universe between two initial/final stable $d{S}_3$ vacua states.
