Some results on effective string description of QCD flux tubes.


Our numerical studies of Flux Tubes in d=3,4 QCD and the strong evidence thereby for them being described by free Bosonic String theory to order R^-3, where R is the string length, will be briefly reviewed. The Polchinski-Strominger Effective String Theory approach and our recent work in constructing them to all orders will then be described. A proof will be presented that to all orders the entire class of these theories has the same spectrum as free Bosonic String Theory. I will also discuss our ongoing investigations to compliment these results on the basis of canonical QFT and I will conclude by discussing the implications for our understanding of QCD-Strings.
