      R2 inflation from scale invariant supergravity and anomaly free superstrings with fluxes 

      Lüst, Dieter; Kounnas, Costas; Toumbas, Nicolaos K. (2015)
      The R2 scale invariant gravity theory coupled to conformally invariant matter is investigated. We show that in the non-supersymmetric case the conformally coupled scalars belong to an SO(1,1+n)/SO(1+n) manifold, while in ...
