“…Generically, the more supersymmetry is retained the more checks of their agreement with field theory exist. For example, a flow to an N = 2 theory can be found by giving equal mass to four of the six scalars and two of the four gauginos of the N = 4 theory [58][59][60]. This theory is called the N = 2 * theory and the induced flow of the dilaton can be matched to the expected running coupling behaviour of the field theory [61,62].…”

Abstract. We review recent progress in studying mesons within gauge/gravity duality, in the context of adding flavour degrees of freedom to generalizations of the AdS/CFT correspondence. Our main focus is on the "top-down approach" of considering models constructed within string theory. We explain the stringtheoretical constructions in detail, aiming at non-specialists. These give rise to a new way of describing strongly coupled confining large-N gauge theories similar to large-N QCD. In particular, we consider gravity dual descriptions of spontaneous chiral symmetry breaking, and compare with lattice results. A further topic covered is the behaviour of flavour bound states in finite-temperature field theories dual to a gravity background involving a black hole. We also describe the "bottom up" phenomenological approach to mesons within AdS/QCD. Some previously unpublished results are also included.PACS. 11.15.-q Gauge field theories -11.25.Tq Gauge/string duality -12.40.Yx Hadron mass models and calculations -14.40.-n Mesons

“…We begin with description of the PW effective action [1], and its gravitational RG flows dual to N = 2 * plasma at strong coupling [12,13]. The action of the effective five-dimensional gauged supergravity including the scalars α and χ (dual to mass terms for the bosonic and fermionic components of the hypermultiplet respectively) is given by…”

“…In [1] Pilch and Warner (PW) proposed a holographic renormalization group flow dual to N = 2 supersymmetric SU(N ) gauge theory, obtained by turning on a mass term for the N = 2 hypermultiplet of the parental N = 4 SU(N ) supersymmetric Yang-Mills theory. This massive deformation of N = 4 SYM is commonly referred to as N = 2 * theory.…”

Although Pilch-Warner (PW) gravitational renormalization group flow [1] passes a number of important consistency checks to be identified as a holographic dual to a large-N SU(N ) N = 2 * supersymmetric gauge theory, it fails to reproduce the free energy of the theory on S 4 , computed with the localization techniques. This disagreement points to the existence of a larger dual gravitational consistent truncation, which in the gauge theory flat-space limit reduces to a PW flow. Such truncation was recently identified by Bobev-Elvang-Freedman-Pufu (BEFP) [2]. Additional bulk scalars of the BEFP gravitation truncation might lead to destabilization of the finite-temperature deformed PW flows, and thus modify the low-temperature thermodynamics and hydrodynamics of N = 2 * plasma. We compute the quasinormal spectrum of these bulk scalar fields in the thermal PW flows and demonstrate that these modes do not condense, as long as the masses of the N = 2 * hypermultiplet components are real.

We consider the holographic dual of a general class of N = 1 * flows in which all three chiral multiplets have independent masses, and in which the corresponding Yang-Mills scalars can develop particular supersymmetry-preserving vevs. We also allow the gaugino to develop a vev. This leads to a six parameter subspace of the supergravity scalar action, and we show that this is a consistent truncation, and obtain a superpotential that governs the N = 1 * flows on this subspace. We analyse some of the structure of the superpotential, and check consistency with the asymptotic behaviour near the UV fixed point. We show that the dimensions of the six couplings obey a sum rule all along the N = 1 * flows. We also show how our superpotential describes part of the Coulomb branch of the non-trivial N = 1 fixed point theory.
