Abstract: A method of determining the mass spectrum of BPS Dbranes in any phase limit of a gauged linear sigma model is introduced. A ring associated to monodromy is defined and one considers Ktheory to be a module over this ring. A simple but interesting class of hybrid models with LandauGinzburg fibres over ℙnare analyzed using special Kähler geometry and Dbrane probes. In some cases the hybrid limit is an infinite distance in moduli space and corresponds to a decompactification. In other cases the hybrid limit is at a finite distance and acquires massless Dbranes. An example studied appears to correspond to a novel theory of supergravity with an SU(2) gauge symmetry where the gauge and gravitational couplings are necessarily tied to each other. © SISSA 2010.
