Supersymmetry breaking at the end of a cascade of Seiberg dualities
M. Bertolini, F. Bigazzi, A. L. Cotrone
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 h…
Gauge theory description of compactified pp-waves
M. Bertolini, J. de Boer, T. Harmark +2
We find a new Penrose limit of AdS_5*S^5 that gives the maximally symmetric pp-wave background of type IIB string theory in a coordinate system that has a manifest space-like isome…
Non-extremal fractional branes
M. Bertolini, T. Harmark, N. A. Obers +1
We construct non-extremal fractional D-brane solutions of type-II string theory at the Z_2 orbifold point of K3. These solutions generalize known extremal fractional-brane solution…
More Anomalies from Fractional Branes
M. Bertolini, P. Di Vecchia, M. Frau +2
In this note we show how the anomalies of both pure and matter coupled N=1,2 supersymmetric gauge theories describing the low energy dynamics of fractional branes on orbifolds can…
Fractional Branes and N=1 Gauge Theories
M. Bertolini, P. Di Vecchia, G. Ferretti +1
We discuss fractional D3-branes on the orbifold C^3/Z_2*Z_2. We study the open and the closed string spectrum on this orbifold. The corresponding N=1 theory on the brane has, gener…
Real Special Geometry
M. Bertolini, A. Ceresole, R. D'Auria +1
We give a coordinate-free description of real manifolds occurring in certain four dimensional supergravity theories with antisymmetric tensor fields. The relevance of the linear mu…
