# Massive 3D Gravity Big-Bounce - High Energy Physics - Theory

Abstract: The properties of an extension of the New Massive 3D Gravity by scalar matterwith Higgs-like self-interaction are investigated. Its perturbative unitarityconsistency is verified for a family of cosmological Bounce solutions found bythe superpotential method. They correspond to the lower bound ${\lambda = -1}$of the BHT unitarity window and describe eternally accelerated 3D Universebetween two initial-final stable $dS 3$ vacua states.
