D-Instantons in Non-Critical Open String Theory
arXiv:hep-th/9706069 · doi:10.1016/S0370-2693(97)01006-X
Abstract
We show that the strength of the leading non-perturbative effects in non-critical string theory is of the order $e^{-O(1/{β_{st}})}$. We show how this restricts the space of consistent theories. We also identify non-critical one dimensional D-instantons as dynamical objects which exchange closed string states and calculate the order of their size.
