The Moduli Space of Cp 1 Stringy Cosmic Lumps


We examine the low-energy dynamics of CP 1 lumps coupled to gravity, taking into account the gravitational back-reaction of the spacetime geometry. We show that the single lump moduli space is equipped with a three-dimensional metric, and we derive stability bounds on the scalar coupling constant. We also derive an expression for the multi-lump moduli space… (More)
