“…However, in most cases we will find that the effective tension T eff vanishes for small ρ. As discussed in section 3, this means that only the lower limit of the integral (24) contributes to L(ρ). The limiting behaviour of L(ρ 0 ) for small ρ 0 is therefore presumably insensitive to changes to the UV.…”

“…The analysis of [23] describes a system of solutions related by a chain of dualities, together with a boost in eleven dimensions. More specifically, the 'unrotated' solution, obtained by setting the boost parameter β = 0, corresponds D5 branes wrapping the S 2 of the resolved conifold [24], and is a simpler limit of the solution with general β as introduced in [25]. This has additional D3 brane charges which are not present in the 'unrotated' case.…”

We calculate quark-antiquark potentials using the relationship between the expectation value of the Wilson loop and the action of a probe string in the string dual. We review and categorize the possible forms of the dependence of the energy on the separation between the quarks. In particular, we examine the possibility of there being a minimum separation for probe strings which do not penetrate close to the origin of the bulk space, and derive a condition which determines whether this is the case. We then apply these considerations to the flavoured resolved deformed conifold background of Gaillard et al [1]. We suggest that the unusual behaviour we observe in this solution is likely to be related to the IR singularity which is not present in the unflavoured case.

“…At zero temperatures these gravity duals are studied in [8] with, and in [7] without, fundamental flavors. On the other hand, at high temperatures, there are examples of gravity duals with or without fundamental flavors in the literature [10,11,12,13], all of which are quite successful in analyzing various aspects of strongly coupled nuclear matter in the IR. But each of the models have their limitations, most prominently due to the absence of UV completions, and a supergravity description for strongly coupled QCD incorporating various phases of quark matter is yet to be discovered.…”

Abstract. We summarize the dual gravity description for a thermal gauge theory, reviewing the key features of our holographic model of large N QCD [3,4] and elaborating on some new results. The theory has matter in the fundamental representation and the gauge coupling runs logarithmically with energy scale at low energies. At the highest energies the theory becomes approximately scale invariant, much like what we would expect for large N QCD although not with asymptotic freedom. In this limit the theory has a gravity dual captured by an almost classical supergravity description with a controlled quantum behavior, such that by renormalizing the supergravity action, we can compute the stress tensor of the dual gauge theory. From the stress tensor we obtain the shear viscosity and the entropy of the medium at a temperature T , and the violation of the bound for the viscosity to the entropy ratio is then investigated. By considering dynamics of open strings in curved spacetime described by the supergravity limit, we compute the drag and diffusion coefficients for a heavy parton traversing the thermal medium. It is shown that both coefficients have a logarithmic dependence on momentum, consistent with pQCD expectations. Finally, we study the confinement/deconfinement mechanism for quarks by analyzing open strings in the presence of the flavor seven branes. We find linear confinement of quarks at low temperatures, while at high temperatures the quarkonium states melt, a behavior consistent with the existence of a deconfined phase.

“…For the case of wrapped brane set-ups dual to a version of N = 1 SYM theory [7], the addition of flavors was first considered in the limit → 0 (similar to the quenched approximation in the Lattice) in [11]. In the papers [9] and [12] the full dynamics of fundamentals was taken into account, by working in the so called Veneziano scaling, that is considering x = N f Nc fixed, in the large N c limit. The field theory dual to the backgrounds in [9] and [12] is a version of N = 1 SQCD on which we will elaborate below.…”

Remarks on the string dual toN=1supersymmetric QCD

We study the String dual to N = 1 SQCD deformed by a quartic superpotential in the quark superfields. We present a unified view of the previous results in the literature and find new exact solutions and new asymptotic solutions. Then we study the Physics encoded in these backgrounds, giving among other things a resolution to an old puzzle related to the beta function and a sufficient criteria for screening. We also extend our results to the SO(N c ) case where we present a candidate for the Wilson loop in the spinorial representation. Various aspects of this line of research are critically analyzed.
