We employ the string/gauge theory correspondence to study properties of strongly coupled quark-gluon plasmas in thermal gauge theories with a large number of colors and flavors. In particular, we analyze noncritical string duals of conformal (S)QCD, as well as ten-dimensional wrapped fivebrane duals of SQCD-like theories. We study general properties of the dual plasmas, including the drag force exerted on a probe quark and the jet quenching parameter. We find that these plasma observables… 

In-Medium Effects in the Holographic Quark-Gluon Plasma

We use the gauge/gravity duality to investigate various properties of strongly coupled gauge theories, which we interpret as models for the quark-gluon plasma (QGP). In particular, we use variants of

D3-D7 Quark-Gluon Plasmas

We present the string dual to finite temperature SU(Nc) = 4 SYM coupled to massless fundamental matter introduced by Nf D7 branes, with Abelian flavor symmetry. The analytic solution includes the

The Klebanov-Strassler model with massive dynamical flavors

We present a fully backreacted D3-D7 supergravity solution dual to the Klebanov-Strassler cascading gauge theory coupled to a large number of massive dynamical flavors in the Veneziano limit. The

Screening effects on meson masses from holography

We study the spectra of scalar and vector mesons in four dimensional strongly coupled SQCD-like theories in the Veneziano limit. The gauge theories describe the low energy dynamics of intersecting D3

A holographic model for large N thermal QCD

We summarize the dual gravity description for a thermal gauge theory, reviewing the key features of our holographic model of large N QCD (Mia et al 2010 Nucl. Phys. B 839 187, Mia et al 2010 Phys.

Glueball spectra of SQCD-like theories

We study the spectrum of scalar glueballs in SQCD-like theories whose gravity description is in terms of Nc D5 color branes wrapped on an S2 inside a CY3-fold, and Nf backreacting D5 flavor branes

Calculating the jet quenching parameter in the plasma of NCYM theory from gauge/gravity duality

A particular decoupling limit of the nonextremal (D1, D3) brane bound state system of type IIB string theory is known to give the gravity dual of space-space noncommutative Yang-Mills theory at



Towards a holographic dual of large- N c QCD

We study N f D6-brane probes in the supergravity background dual to N c D4-branes compactified on a circle with supersymmetry-breaking boundary conditions. In the limit in which the resulting

Non-critical holography and four-dimensional CFT's with fundamentals

We find non-critical string backgrounds in five and eight dimensions, holographically related to four-dimensional conformal field theories with = 0 and = 1 supersymmetries. In the five-dimensional

Photon and dilepton production in supersymmetric Yang-Mills plasma

By weakly gauging one of the U(1) subgroups of the R-symmetry group, = 4 super-Yang-Mills theory can be coupled to electromagnetism, thus allowing a computation of photon production and related

Chiral symmetry breaking and pions in nonsupersymmetric gauge / gravity duals

We study gravity duals of large N nonsupersymmetric gauge theories with matter in the fundamental representation by introducing a D7-brane probe into deformed AdS backgrounds. In particular, we

We study the screening length Ls of a heavy quark-antiquark pair in strongly coupled gauge theory plasmas flowing at velocity v. Using the AdS/CFT correspondence we investigate, analytically, the

Fundamental matter, meson spectroscopy and non-critical string/gauge duality

We discuss the incorporation of quarks in the fundamental representation of the color group into the non-critical string/gauge duality. We focus on confining theories and address this question using

Thermodynamics of AdS/QCD

We study finite temperature properties of four dimensional QCD-like gauge theories in the gauge theory/gravity duality picture. The gravity dual contains two deformed 5d AdS metrics, with and without
