Gravitational Approach to Tachyon Matter
arXiv:hep-th/0207004 · doi:10.1103/PhysRevD.66.125009
Abstract
We found a gravity solution of p+1 dimensional extended object with SO(p)xSO(9-p) symmetry which has zero pressure and zero dilaton charge. We expect that this object is a residual tachyon dust after tachyon condensation of brane and anti-brane system discussed by Sen, recently. We also discuss the Hawking temperature and some properties of this object.
