Title: From things to strings?

Abstract: 
I propose a bottom-up approach to color confinement and gauge/string 
duality in real-life QCD, starting from the ordinary Yang-Mills 
theory. Specifically, I will show how one can organize the Yang-Mills 
Lagrangian as a perturbation of a N=2 Super Yang-Mills Lagrangian. 
The existence of this supersymmetric core inside the ordinary 
Yang-Mills theory suggests a dynamical realization of the dual 
superconductor mechanism for color confinement. It may also explain 
why the non perturbative physics of the deconfined Quark-Gluon Plasma 
phase of QCD observed at the RHIC accelerator closely resembles that 
of a supersymmetric theory as computed via gauge/string duality 
techniques.
