O'Raifeartaigh models with spontaneous R-symmetry breaking
Luca Ferretti
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…

Non-Abelian vortices and monopoles in SO(N) theories
Luca Ferretti, Sven Bjarke Gudnason, Kenichi Konishi
Non-Abelian BPS vortex solutions are constructed in N=2 theories with gauge groups SO(N)\times U(1). The model has N_f flavors of chiral multiplets in the vector representation of…

R-symmetry breaking, runaway directions and global symmetries in O'Raifeartaigh models
Luca Ferretti
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…
