  • 3D superconformal theories from Sasakian seven-manifolds: new nontrivial evidences for AdS_4/CFT_3
    Fabbri, Davide; Fre', Pietro; Gualtieri, Leonardo; Reina, Cesare; Tomasiello, Alessandro; Zaffaroni, Alberto; Zampa, Alessandro (SISSA Library, 1999)
  • ALE manifolds and Conformal Field Theory
    Anselmi, Damiano; Billo', Marco; Fre', Pietro; Girardello, Luciano; Zaffaroni, Alberto (World Scientific, 1994-07-10)
    We address the problem of constructing the family of (4,4) theories associated with the sigma-model on a parametrized family ${\cal M}_{\zeta}$ of Asymptotically Locally Euclidean (ALE) manifolds. We rely on the ADE ...
  • Baryonic Generating Functions
    Forcella, Davide; Hanany, Amihay; Zaffaroni, Alberto (2007-03-01)
    We show how it is possible to use the plethystic program in order to compute baryonic generating functions that count BPS operators in the chiral ring of quiver gauge theories living on the world volume of D branes probing ...
  • Counting BPS Baryonic Operators in CFTs with Sasaki-Einstein duals
    Butti, Agostino; Forcella, Davide; Zaffaroni, Alberto (2006-11-23)
    We study supersymmetric D3 brane configurations wrapping internal cycles of type II backgrounds AdS(5) x H for a generic Sasaki-Einstein manifold H. These configurations correspond to BPS baryonic operators in the dual ...
  • Counting Chiral Operators in Quiver Gauge Theories
    Butti, Agostino; Forcella, Davide; Hanany, Amihay; Vegh, David; Zaffaroni, Alberto (2007-05-31)
    We discuss in detail the problem of counting BPS gauge invariant operators in the chiral ring of quiver gauge theories living on D-branes probing generic toric CY singularities. The computation of generating functions that ...
  • Deformations of conformal theories and non-toric quiver gauge theories
    Butti, Agostino; Forcella, Davide; Zaffaroni, Alberto (2006-07-26)
    We discuss several examples of non-toric quiver gauge theories dual to Sasaki-Einstein manifolds with U(1)^2 or U(1) isometry. We give a general method for constructing non-toric examples by adding relevant deformations ...
  • Finite Gauge Theories
    Zaffaroni, Alberto (SISSA, 1994-10-27)
  • The Master Space of N=1 Gauge Theories
    Forcella, Davide; Hanany, Amihay; He Yang-Hui; Zaffaroni, Alberto (2008-01-14)
    The full moduli space M of a class of N=1 supersymmetric gauge theories is studied. For gauge theories living on a stack of D3-branes at Calabi-Yau singularities X, M is a combination of the mesonic and baryonic branches, ...
  • Master space, Hilbert series and Seiberg duality
    Forcella, Davide; Hanany, Amihay; Zaffaroni, Alberto (IOP Publishing, 2009-07)
    We analyze the action of Toric (Seiberg) duality on the combined mesonic and baryonic moduli space of quiver gauge theories obtained from D3 branes at Calabi-Yau singularities. We analyze in particular the structure of the ...
  • Mastering the Master Space
    Forcella, Davide; Hanany, Amihay; He Yang-Hui; Zaffaroni, Alberto (2008-02-18)
    Supersymmetric gauge theories have an important but perhaps under-appreciated notion of a master space, which controls the full moduli space. For world-volume theories of D-branes probing a Calabi-Yau singularity X the ...
  • Moduli Space and Chiral Ring of D3 Branes at Singularities
    Forcella, Davide (SISSA, 2008-09-17)
  • On the geometry and the moduli space of beta-deformed quiver gauge theories
    Butti, Agostino; Forcella, Davide; Martucci, Luca; Minasian, Ruben; Petrini, Michela; Zaffaroni, Alberto (2007-12-10)
    We consider a class of super-conformal beta-deformed N=1 gauge theories dual to string theory on $AdS_5 \times X$ with fluxes, where $X$ is a deformed Sasaki-Einstein manifold. The supergravity backgrounds are explicit ...
