    New results for AdS/CFT and beyond
    (2005) Bertolini, Matteo; Bigazzi, Francesco; Cotrone, Aldo Lorenzo; Physics; Elementary Particle Theory
    We report on some recent results within the string/gauge theory correspondence, both in the conformal and in the non conformal cases, for a recently found class of N=1 dual pairs. These results provide the first cross check of AdS/CFT and field theory techniques like a-maximization. Moreover, they furnish new examples of cascading gauge theories and the first instance of 4d dynamical supersymmetry breaking embedded in the correspondence

    Supersymmetry breaking at the end of a cascade of Seiberg dualities
    (2005) Bertolini, Matteo; Bigazzi, Francesco; Cotrone, Aldo Lorenzo; Physics; Elementary Particle Theory
    We study the IR dynamics of the cascading non-conformal quiver theory on N regular and M fractional D3 branes at the tip of the complex cone over the first del Pezzo surface. The horizon of this cone is the irregular Sasaki-Einstein manifold Y 2,1. Our analysis shows that at the end of the cascade supersymmetry is dynamically broken.
