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…
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…
The dual superconformal theory for Lpqr manifolds
Agostino Butti, Davide Forcella, Alberto Zaffaroni
We present the superconformal gauge theory living on the world-volume of D3 branes probing the toric singularities with horizon the recently discovered Sasaki-Einstein manifolds L^…
The Baryonic Branch of Klebanov-Strassler Solution: a Supersymmetric Family of SU(3) Structure Backgrounds
Agostino Butti, Mariana Graña, Ruben Minasian +2
We exhibit a one-parameter family of regular supersymmetric solutions of type IIB theory that interpolates between Klebanov-Strassler (KS) and Maldacena-Nunez (MN). The solution is…
The scaling equation of state of the three-dimensional O(N) universality class: N >= 4
Agostino Butti, Francesco Parisen Toldin, Andrea Pelissetto +1
We determine the critical equation of state of the three-dimensional O(N) universality class, for N=4, 5, 6, 32, 64. The N=4 is relevant for the chiral phase transition in QCD with…
