We construct Dp-branes in bosonic string theory as unstable lumps in a truncated string field theory of open strings on a D25-brane. We find that the lowest level truncation gives good quantitative agreement with the predicted D-brane tension and low-lying spectrum of the D-brane 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 D-brane arises through a mechanism reminiscent of the Randall-Sundrum mechanism for gravity.

The paper

Original abstract

We construct Dp-branes in bosonic string theory as unstable lumps in a truncated string field theory of open strings on a D25-brane. We find that the lowest level truncation gives good quantitative agreement with the predicted D-brane tension and low-lying spectrum of the D-brane 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 D-brane arises through a mechanism reminiscent of the Randall-Sundrum mechanism for gravity.

Analytic solution for tachyon condensation in open string field theory
hep-th 2005-11 accept novelty 8.0 of 10

An exact analytic solution of Witten's cubic open string field theory is constructed for the tachyon vacuum, and Sen's first conjecture (vacuum energy equals minus D-brane tension) is proved analytically.
Boundary String Field Theory of the DDbar System
hep-th 2000-12 conditional novelty 6.0 of 10

The Ramond-Ramond couplings of a brane-antibrane pair are derived from boundary string field theory and shown to equal the supertrace of the exponential of Quillen's superconnection curvature.
Tachyon Dynamics in Open String Theory
hep-th 2004-10 accept novelty 2.0 of 10

A comprehensive review of open string tachyon condensation argues that unstable D-brane dynamics is captured by an internally consistent open string field theory without explicit closed-string coupling.
D-Branes, Tachyons, and String Field Theory
hep-th 2003-11 accept novelty 2.0 of 10

Witten's cubic open string field theory reproduces the Sen tachyon-condensation picture, with level-truncated solutions approaching the D-brane tension and no open-string cohomology in the stable vacuum.

2 arXiv papers cite this in 2 sentences

Each citing sentence is taken from the citing paper's LaTeX source and typed by Pith's classifier. A label appears at probability 0.8 or more (0.95 for support), a contest at 0.7 or more; the quoted words are the citing authors'. How each label was checked · JSON

Cites it as background 1 paper

For example, in bosonic open string field theory, Sen conjectured that D$p$-branes with $p<25$ are described as unstable lump solutions [ref] and this was tested in many papers starting with [ref] [ref] [ref] .
