Fundamental String Solutions in Open String Field Theories

High Energy Physics - Theory 2008-11-26 v4

Abstract

In Witten's open cubic bosonic string field theory and Berkovits' superstring field theory we investigate solutions of the equations of motion with appropriate source terms, which correspond to Callan-Maldacena solution in Born-Infeld theory representing fundamental strings ending on the D-branes. The solutions are given in order by order manner, and we show some full order properties in the sense of (alpha)'-expansion. In superstring case we show that the solution is 1/2 BPS in full order.
