Abstract

We study DBI-type effective theory of an unstable D3-brane in the background manifold ℝ1,1 × M2 where M 2 is an arbitrary two-dimensional manifold. We obtain an exact tubular D2-brane solution of arbitrary cross sectional shape by employing 1/ cosh tachyon potential. When M2 = S2, the solution is embedded in the background geometry ℝ1,3 × S2 of Salam-Sezgin model. This tachyon potential shows a unique property that an array of tachyon soliton solutions has a fixed period which is independent of integration constants of the equations of motion. The thin BPS limit of the configurations leads to supertubes of arbitrary cross sectional shapes.
