Black-hole quasinormal modes and scalar glueballs in a finite-temperature AdS/QCD model

We use the holographic AdS/QCD soft-wall model to investigate the spectrum of scalar glueballs in a finite temperature plasma. In this model, glueballs are described by a massless scalar field in an…

Deep inelastic scattering for vector mesons in holographic D4-D8 model

We study deep inelastic scattering for vector and axial vector mesons in the holographic D4-D8 brane model. We consider tree level contributions with one particle in the final hadronic state. We…

Gauge/string duality and scalar glueball mass ratios

It has been shown by Polchinski and Strassler that the scaling of high energy QCD scattering amplitudes can be obtained from string theory. They considered an AdS slice as an approximation for the…

Glueball Regge trajectories from gauge-string duality and the pomeron

The spectrum of light baryons and mesons has been reproduced recently by Brodsky and Teramond from a holographic dual to QCD inspired in the AdS/CFT correspondence. They associate fluctuations about…

QCD/String holographic mapping and glueball mass spectrum

Abstract.Recently Polchinski and Strassler reproduced the high energy QCD scaling at fixed angles from a gauge string duality inspired by the AdS/CFT correspondence. In their approach a confining…

Deep inelastic scattering from gauge string duality in D3-D7 brane model

We calculate deep inelastic structure functions for mesons in the D3-D7 brane model, that incorporates flavour to the AdS/CFT correspondence. We consider two different prescriptions for the hadronic…

Pion and vector meson form factors in the Kuperstein-Sonnenschein holographic model

We study phenomenological aspects of the holographic model of chiral symmetry breaking recently introduced by Kuperstein and Sonnenschein (KS). As a first step, we calculate the spectrum of vector…

Static strings in Randall-Sundrum scenarios and the quark-antiquark potential

We calculate the energy of a static string in an anti-de Sitter (AdS) slice between two D3-branes with orbifold condition. The energy for configurations with end points on a brane grows linearly for…

Deep inelastic scattering off a plasma with flavor from the D3-D7 brane model

We investigate the propagation of a spacelike flavor current in a strongly coupled $\mathcal{N}=2$ super Yang-Mills plasma using the D3-D7 brane model at finite temperature. The partonic contribution…

Hadronic spectra from deformed AdS backgrounds

Because of the presence of modified warp factors in metric tensors, we use deformed AdS5 spaces to apply the AdS/CFT correspondence to calculate the spectra for even and odd glueballs, scalar and…
