D72 (2005) 061902https://openscience.sissa.it/handle/1963/1735We 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.144376 bytesapplication/pdfen-USPreprint
