O'Raifeartaigh models with spontaneous R-symmetry breaking
Luca Ferretti
文献摘要
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.
