O’Raifeartaigh models with spontaneous R-symmetry breaking
O’Raifeartaigh models with general R-charge assignments can have vacua where both supersymmetry and R-symmetry are spontaneously broken. Most of these vacua are metastable because the potential shows a runaway behaviour. We explain the relation between runaway directions and R-symmetry. PACS. 11.30.Qc -12.60.Jv
متن کاملSpontaneous R-Symmetry Breaking in O’Raifeartaigh Models
We study the question of whether spontaneous U(1)R breaking can occur in O’Raifeartaightype models of spontaneous supersymmetry breaking. We show that in order for it to occur, there must be a field in the theory with R-charge different from 0 or 2. We construct the simplest O’Raifeartaigh model with this property, and we find that for a wide range of parameters, it has a meta-stable vacuum whe...

متن کاملNonperturbative Spontaneous Symmetry Breaking
One of the most astonishing results of quantum field theory is spontaneous symmetry breaking. One can say that it is the situation when something arises from the quantization. This means that on the quantum level one has something that was not present on the classical level. Coleman and Weinberg [1] write : “ . . . higher-order effects may qualitatively change the character of a physical theory...
