Energy loss of a heavy quark moving through Script N = 4 supersymmetric Yang-Mills plasma

We use the AdS/CFT correspondence to determine the rate of energy loss of a heavy quark moving through = 4 SU(Nc) supersymmetric Yang-Mills plasma at large 't Hooft coupling. Using the dual… Expand

Linear confinement and AdS/QCD

- A. Karch, E. Katz, D. Son, M. Stephanov
- Physics
- 26 February 2006

In a theory with linear confinement, such as QCD, the masses squared m^2 of mesons with high spin S or high radial excitation number n are expected, from semiclassical arguments, to grow linearly… Expand

Adding flavor to AdS/CFT

Coupling fundamental quarks to QCD in the dual string representation corresponds to adding the open string sector. Flavors therefore should be represented by space-time filling D-branes in the dual… Expand

Modeling the fifth dimension with scalars and gravity

- O. Dewolfe, D. Freedman, S. Gubser, A. Karch
- Physics
- 20 September 1999

A method for obtaining solutions to the classical equations for scalars plus gravity in five dimensions is applied to some recent suggestions for brane-world phenomenology. The method involves only… Expand

Open and closed string interpretation of SUSY CFT's on branes with boundaries

- A. Karch, L. Randall
- Physics
- 14 May 2001

We consider certain supersymmetric configurations of intersecting branes and branes ending on branes and analyze the duality between their open and closed string interpretation. The examples we study… Expand

Metallic AdS/CFT

- A. Karch, A. O’Bannon
- Physics
- 26 May 2007

We use the AdS/CFT correspondence to compute the conductivity of massive = 2 hypermultiplet fields at finite baryon number density in an = 4 SU(Nc) super-Yang-Mills theory plasma in the large Nc,… Expand

Locally localized gravity

- A. Karch, L. Randall
- Physics
- 16 November 2000

We study the fluctuation spectrum of linearized gravity around non-fine-tuned branes. We focus on the case of an AdS4 brane in AdS§. In this case, for small cosmological constant, the warp factor… Expand

Branes at orbifolds versus Hanany Witten in six dimensions

- I. Brunner, A. Karch
- Physics
- 15 December 1997

We reconstruct non-trivial 6d theories obtained by Blum and Intriligator by considering IIB or SO(32) 5 branes at ALE spaces in the language of Hanany-Witten setups. Using ST duality we make the… Expand

LOCALLY LOCALIZED GRAVITY

- A. Karch, L. Randall
- Physics
- 20 February 2001

We study the fluctuation spectrum of linearized gravity around non-fine-tuned branes. We focus on the case of an AdS4 brane in AdS5. In this case, for small cosmological constant, the warp factor… Expand
