Abstract
The most straightforward use of AdS/CFT correspondence gives versions of QCD where quarks are in adjoint representations. Using an asymmetric orbifold approach we obtain nonsupersymmetric QCD with four quark flavors in fundamental representations of color.
Highlights
The interplay between gauge field theories and string theory is one of the most fertile in high-energy theory
It may be used to study quantum chromodynamics (QCD) and very interesting results have been obtained by Polchinski and Strassler [9,10,11] about the relationship of QCD to string theory from the AdS/CFT correspondence
This is of special interest in view of the above history because the string theory was originally displaced by QCD thirty years ago
Summary
The interplay between gauge field theories and string theory is one of the most fertile in high-energy theory. This correspondence provides a powerful tool to investigate gauge field theory. Of whether the superstring can provide a correct theory of quantum gravity the AdS/CFT correspondence can suggest interesting models for non-gravitational physics.
