Branes and Dynamical Supersymmetry Breaking
We study dynamical supersymmetry breaking in four dimensions using the fivebrane of M theory, in particular for the Izawa-Yanagida-Intriligator-Thomas (IYIT) model, which we realize as the worldvolume theory of a certain M-theory fivebrane configuration. From the brane point of view, supersym-metry is broken when a holomorphic configuration with the proper boundary conditions does not exist. We...
متن کاملD-Terms and Supersymmetry Breaking from Branes
Metastable supersymmetry breaking configurations of D-branes and NS5-branes in string theory often owe their existence to classical gravitational interactions between the branes. We show that in the effective theory of the light fields, these interactions give rise to a noncanonical Kähler potential and other D-terms. String theory provides a UV completion in which these non-renormalizable term...
متن کاملD-branes, Supersymmetry Breaking, and Neutrinos
This thesis studies metaand exactly stable supersymmetry breaking mechanisms in heterotic and type IIB string theories and constructs an F-theory Grand Unified Theory model for neutrino physics in which neutrino mass is determined by the supersymmetry breaking mechanism. Focussing attention on heterotic string theory compactified on a 4-torus, stability of non-supersymmetric states is studied. ...

متن کاملCONDITIONS ON SUPERSYMMETRY SOFT-BREAKING TERMS FROM GUTs
We study the effect of integrating out the heavy fields in a supersymmetric GUT which does not contain small mass parameters in the limit of exact supersymmetry. The trilinear (A) and bilinear (B) coefficients of the supersymmetry soft-breaking terms of the low-energy effective theory are related in a simple and model-independent way to those of the underlying theory. From these relations, we o...
