Novel Extension of MSSM and ``TeV Scale'' Coupling Unification

Zurab Kakushadze

Motivated by the coupling unification problem, we propose a novel extension of the Minimal Supersymmetric Standard Model. One of the predictions of this extension is existence of n…

Remarks on Two-Loop Free Energy in N=4 Supersymmetric Yang-Mills Theory at Finite Temperature

A. Fotopoulos, T. R. Taylor

The strong coupling behavior of finite temperature free energy in N=4 supersymmetric SU(N) Yang-Mills theory has been recently discussed by Gubser, Klebanov and Tseytlin in the con…

Brane World

Zurab Kakushadze, S. -H. Henry Tye

In string theory, the brane world scenario, where the Standard Model gauge and matter fields live inside some branes while gravitons live in the bulk, can be a viable description o…

String Expansion as 't Hooft's Expansion

Zurab Kakushadze

We briefly review some recent developments in large N gauge theories which utilize the power of string perturbation techniques.

Large N Gauge Theories from Orientifolds with NS-NS B-flux

Zurab Kakushadze

We consider D-branes and orientifold planes embedded in non-compact (orbifolded) space-time. We point out that even in the non-compact cases we can turn on non-zero (quantized) NS-…

Large N Domain Walls as D-branes for QCD String

Gia Dvali, Zurab Kakushadze

We consider a model which in a certain limit reduces to the large N supersymmetric SU(N) gauge theory without matter. The gaugino condensate in this model is controlle…
