Superstrings in AdS
Luca Mazzucato
This is a comprehensive review of the worldsheet techniques for the quantization of type IIB superstring theory on the AdS_5 x S^5 background, using the pure spinor formalism. Part…
The Konishi multiplet at strong coupling
Brenno Carlini Vallilo, Luca Mazzucato
We introduce a method to compute from first principles the anomalous dimension of short operators in N=4 super Yang-Mills theory at strong coupling, where they are described in ter…
Holographic dual of free field theory
Michael R. Douglas, Luca Mazzucato, Shlomo S. Razamat
We derive a holographic dual description of free quantum field theory in arbitrary dimensions, by reinterpreting the exact renormalization group, to obtain a higher spin gravity th…
Taming the b antighost with Ramond-Ramond flux
Nathan Berkovits, Luca Mazzucato
In the pure spinor formalism for the superstring, the b antighost is necessary for multiloop amplitude computations and is a composite operator constructed to satisfy {Q,b}=T where…
On the Non-renormalization of the AdS Radius
Luca Mazzucato, Brenno Carlini Vallilo
We show that the relation between the 't Hooft coupling and the radius of AdS is not renormalized at one-loop in the sigma model perturbation theory. We prove this by computing the…
Non-relativistic Branes
Luca Mazzucato, Yaron Oz, Stefan Theisen
We construct gravitational non-relativistic brane solutions of type IIA/IIB string theories and M-theory and their near-horizon geometries. The non-relativistic M2 and M5-brane met…
Supersymmetry Breaking Vacua from M Theory Fivebranes
Luca Mazzucato, Yaron Oz, Shimon Yankielowicz
We consider intersecting brane configurations realizing N=2 supersymmetric gauge theories broken to N=1 by multitrace superpotentials, and softly to N=0. We analyze, in the framewo…
Integrability of Type II Superstrings on Ramond-Ramond Backgrounds in Various Dimensions
Ido Adam, Amit Dekel, Luca Mazzucato +1
We consider type II superstrings on AdS backgrounds with Ramond-Ramond flux in various dimensions. We realize the backgrounds as supercosets and analyze explicitly two classes of m…
Remarks on the analytic structure of supersymmetric effective actions
Luca Mazzucato
We study the effective superpotential of N=1 supersymmetric gauge theories with a mass gap, whose analytic properties are encoded in an algebraic curve. We propose that the degree…
Chiral Rings, Anomalies and Electric-Magnetic Duality
Luca Mazzucato
We study electric-magnetic duality in the chiral ring of a supersymmetric U(N_c) gauge theory with adjoint and fundamental matter, in presence of a general confining phase superpot…
The Liouville Geometry of N=2 Instantons and the Moduli of Punctured Spheres
Gaetano Bertoldi, Stefano Bolognesi, Marco Matone +2
We study the instanton contributions of N=2 supersymmetric gauge theory and propose that the instanton moduli space is mapped to the moduli space of punctured spheres. Due to the r…
On the Chiral Ring of N=1 Supersymmetric Gauge Theories
Marco Matone, Luca Mazzucato
We consider the chiral ring of the pure N=1 supersymmetric gauge theory with SU(N) gauge group and show that the classical relation S^{N^2}=0 is modified to the exact quantum relat…
Branched Matrix Models and the Scales of Supersymmetric Gauge Theories
Marco Matone, Luca Mazzucato
In the framework of the matrix model/gauge theory correspondence, we consider supersymmetric U(N) gauge theory with symmetry breaking pattern. Due to the presence of the V…
The Superembedding Origin of the Berkovits Pure Spinor Covariant Quantization of Superstrings
Marco Matone, Luca Mazzucato, Ichiro Oda +2
We show that the pure spinor formalism proposed by Berkovits to covariantly quantize superstrings is a gauge fixed, twisted version of the complexified n=2 superembedding formulati…
