Non-Critical Poincaré Invariant Bosonic String Backgrounds and Closed String Tachyons
E. Alvarez, C. Gomez, L. Hernandez
A new family of non critical bosonic string backgrounds in arbitrary space time dimension and with Poincaré invariance are presented. The metric warping factor and…

Non-Critical Confining Strings and the Renormalization Group
E. Alvarez, C. Gomez
String vacua for non critical strings satisfying the requirements of Zig-Zag invariance are constructed. The Liouville mode is shown to play the rôle of scale in the Renormalizatio…

String Representation of Wilson Loops
E. Alvarez, C. Gomez, T. Ortin
We explore the consequences of imposing Polyakov's zig/zag-invariance in the search for a confining string. We first find that the requirement of zig/zag-invariance seems to be inc…
