D-brane States and Annulus Amplitudes in OSp Invariant Closed String Field Theory

arXiv:0805.3744 · doi:10.1088/1126-6708/2008/07/046

Abstract

In the OSp invariant closed string field theory, we construct the states corresponding to parallel D-branes that are located at different points in the space-time. Using these states, we evaluate annulus amplitudes. We show that the results coincide with those of first quantized string theory.
