R-symmetry breaking, runaway directions and global symmetries in O’Raifeartaigh models
We discuss O’Raifeartaigh models with general R-charge assignments, introduced by Shih to break R-symmetry spontaneously. We argue that most of these models have runaway directions related to the R-symmetry. In addition, we study the simplest model with a U(N) global symmetry and show that in a range of parameters Rsymmetry is spontaneously broken in a metastable vacuum.
متن کاملEnhanced symmetry points and metastable supersymmetry breaking along pseudo-runaway directions
We construct a model with long-lived metastable vacua in which all the relevant parameters, including the supersymmetry breaking scale, are generated dynamically by dimensional transmutation. The metastable vacua appear along a pseudo-runaway direction near a point of enhanced symmetry as a result of a balance between non-perturbative and perturbative quantum effects. We show that metastable su...
متن کاملEvolution: Cichlid Models on the Runaway to Speciation
Rapid speciation has fascinated biologists for a long time. A recent study shows that ecological opportunity and sex-biased color differences increase the likelihood of speciation in African cichlid fishes.
متن کاملFlat Directions in Z2n Orbifold Models
We study generic features related to matter contents and flat directions in Z2n orbifold models. It is shown that Z2n orbifold models have massless conjugate pairs, R and R, in certain twisted sectors as well as one of untwisted subsectors. Using these twisted sectors, Z2n orbifold models are classified into two types. Conjugate pairs, R and R, lead to D-flatness as 〈R〉 = 〈R〉 6 = 0. We investig...
متن کاملResearch directions in interpretable machine learning models
The theoretical novelty of many machine learning methods leading to high performing algorithms has been substantial. However, the black-box nature of much of this body of work has meant that the models are difficult to interpret, with the consequence that the significant developments in machine learning theory are not matched by their practical impact. This tutorial stresses the need for interp...
