Dynamical Supersymmetry Breaking
We review mechanisms of dynamical supersymmetry breaking. Several observations that narrow the search for possible models of dynamical supersymmetry breaking are summarized. These observations include the necessary and sufficient conditions for supersymmetry breaking. The two conditions are based on non-rigorous arguments, and we show examples where they are too restrictive. Dynamical effects p...
متن کاملDynamical Supersymmetry Breaking
The ratio of the weak scale to the Planck scale, mW /mPl ∼ 10 , suggests that it should have a dynamical origin. Had this ratio been, e.g., ∼ 10 we would have suspected that the weak scale is a perturbative effect. In fact this ratio is of the right size for a nonperturbative effect in field theory. Had it been extremely small, e.g. ∼ 10 10 or so, we would have to look for some really exotic, u...
متن کاملBranes 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 کاملDynamical Supersymmetry Breaking, with Flavor
We explore calculable models with low-energy supersymmetry where the flavor hierarchy is generated by quark and lepton compositeness, and where the composites emerge from the same sector that dynamically breaks supersymmetry. The observed pattern of Standard Model fermion masses and mixings is obtained by identifying the various generations with composites of different dimension in the ultravio...
متن کاملIssues in Dynamical Supersymmetry Breaking
Recent work has made clear that we have far more control over the dynamics of supersymmetric than non-supersymmetric theories. Here, I discuss some issues in dynamical supersymmetry breaking both in ordinary eld theory and in string theory. In string theory, in particular, it is possible to show, in some circumstances, that stringy non-perturbative eeects are smaller than eeects visible in the ...
