Brane Profiles of Non-Supersymmetric Strings
Abstract
We connect the indications of 2D CFT for branes in non-supersymmetric strings to actual spacetime profiles, taking the bulk tadpole potentials into account. We find exact solutions for the uncharged branes that spread in the internal intervals of Dudas-Mourad vacua for non-tachyonic orientifolds and heterotic strings. These solutions involve suitable dressings of the uncharged branes of the nine-dimensional tadpole-free theory. Similar exact results for uncharged branes that are transverse to the internal space, or for charged branes, appear more challenging. Nevertheless, we identify their large-distance behavior, which is determined by linearized equations, and show that it is compatible with the CFT analysis in all expected cases. We also provide some hints on the leading back-reaction of the form-fields.

Comments
47 pages, LaTeX; corrected some typos and a sign in eq.(4.10), which affects section 4.3. Some of the branes have different behaviors, but the main conclusions are unchanged. Final version to appear in JHEP, with two figures and minor additional text corrections added
