Abstract

We use the non-normalizable complex deformations to describe the stringy realizations of the metastable vacua in N=1, SU(N_c) SUSY theories with N_f>N_c massive fundamental flavors. The consideration of the non-normalizable deformations requires a modified toric duality. The new approach considers the tachyon condensation between pairs of wrapped D5 branes and anti-D5 branes and the resulting mixing between some cycles in the geometry. We enlarge the class of metastable vacua to the case of branes-antibranes wrapped on cycles of deformed A_n singularities.
