Dbranes as unstable lumps in bosonic open string field theory
Abstract
We construct Dpbranes in bosonic string theory as unstable lumps in a truncated string field theory of open strings on a D25brane. We find that the lowest level truncation gives good quantitative agreement with the predicted Dbrane tension and lowlying spectrum of the Dbrane for sufficiently large p and study the effect of the next level corrections for p = 24. We show that a U(1) gauge field zero mode on the Dbrane arises through a mechanism reminiscent of the RandallSundrum mechanism for gravity.
