On The Field Theory Limit Of D-Instantons

High Energy Physics - Theory 2009-10-31 v2

Abstract

We study the dilaton/axion configuration near D-instantons in type IIB superstring theory. In the field theory limit, the metric near the instantons becomes flat in the string frame as well as in the Einstein frame. In the large N limit, the string coupling constant becomes zero except near the origin. The supersymmetry of this configuration is analyzed. An implication of this result to the IIB Matrix Model is discussed.

Comments

Major revision; supersymmetry in Euclidean space re-examined. New conclusions: (1) the supersymmetry is not enhanced in the field theory limit. (2) the theory becomes free type IIB string theory in the large N limit, but the limit is not uniform. 9 pages, LaTeX
