Abstract

In string compactifications, Kahler metrics for chiral matter fields are an essential prerequisite for the computation of soft supersymmetry breaking terms. I describe new techniques for computing these in Calabi-Yau string compactifications. This involves deducing the modular behaviour of the Kahler metric from that of the physical Yukawa couplings. Using these techniques I derive Kahler metrics for both KKLT and large-volume models. For the latter case, I discuss two applications. First, I describe the resulting soft supersymmetry breaking terms and explain why these are naturally flavour-universal. Secondly, I show how the form of the Kahler metric naturally gives the correct phenomenological scale for neutrino masses._x000D_
