We compute the drag force exerted on a quark and a di-quark systems in a background dual to large-N QCD at finite temperature. We find that appears a drag force in the former setup with flow of energy proportional to the mass of the quark while in the latter there is no dragging as in other studies. We also review the screening length.

Holography and Unquenched Quark-Gluon Plasmas

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 non-critical 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 forc...

QCD String as Vortex String in Seiberg-Dual Theory

We construct a classical vortex string solution in a Seiberg-dual theory of N = 1 supersymmetric SO(Nc) QCD which flows to a confining phase. We claim that this vortex string is a QCD string, as previouly argued by M. Strassler. In SO(Nc) QCD, it is known that stable QCD strings exist even in the presence of dynamical quarks. We show that our vortex strings are stable in the Seiberg-dual theory.

New Integrable Structures in Large-N QCD

We study the anomalous dimensions of single trace operators composed of field strengths Fμν in large-N QCD. The matrix of anomalous dimensions is the Hamiltonian of a compact spin chain with two spin one representations at each vertex corresponding to the selfdual and anti-selfdual components of Fμν . Due to the special form of the interaction it is possible to study separately renormalization ...
