On the geometry and the moduli space of beta-deformed quiver gauge theories
Agostino Butti, Davide Forcella, Luca Martucci +3
We consider a class of super-conformal beta-deformed N=1 gauge theories dual to string theory on with fluxes, where is a deformed Sasaki-Einstein manifold. The…
Counting Chiral Operators in Quiver Gauge Theories
Agostino Butti, Davide Forcella, Amihay Hanany +2
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. Th…
Counting BPS Baryonic Operators in CFTs with Sasaki-Einstein duals
Agostino Butti, Davide Forcella, Alberto Zaffaroni
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…
Deformations of conformal theories and non-toric quiver gauge theories
Agostino Butti, Davide Forcella, Alberto Zaffaroni
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 e…
Deformations of Toric Singularities and Fractional Branes
Agostino Butti
Fractional branes added to a large stack of D3-branes at the singularity of a Calabi-Yau cone modify the quiver gauge theory breaking conformal invariance and leading to different…
From Toric Geometry to Quiver Gauge Theory: the Equivalence of a-maximization and Z-minimization
Agostino Butti, Alberto Zaffaroni
AdS/CFT predicts a precise relation between the central charge a, the scaling dimensions of some operators in the CFT on D3-branes at conical singularities and the volumes of the h…
