Scaling the String Tension in a New Class of Regularized String Theories

摘要

We consider two models of discretized string theories with an action which depends on the extrinsic curvature and prove that the string tension vanishes as the coupling strength of the extrinsic curvature tends to infinity. We discuss the physical properties of the models and argue that they possess a nontrivial scaling limit. (ERA citation 13:057884)
