Abstract
The AdS/CFT correspondence of elementary string theory has been recently suggested as a “microscopic” approach to QCD string theory in various dimensions. We use the microscopic theory to show that the ultraviolet regime on the string worldsheet is mapped to the ultraviolet effects in QCD. In the case of QCD_2, a worldsheet path integral representation of QCD strings is known, in terms of a topological rigid string theory whose worldsheet supersymmetry is reminiscent of ParisiSourlas supersymmetry. We conjecture that the supersymmetric rigid string theory is dual to the elementary Type IIB string theory in the singular AdS background that corresponds to the largeN limit of QCD_2. We also generalize the rigid string with worldsheet ParisiSourlas supersymmetry to dimensions greater than two, and argue that the theory is asymptotically free, a nonzero string tension is generated dynamically through dimensional transmutation, and the theory is topological only asymptotically in the ultraviolet.
