Metamorphosis Of Tachyon Profile In Unstable D9-Branes | | Koji Hashimoto

25 Feb 2001 | | Journal: | Phys.Rev. D65 (2002) 026006 | | Subject: | hep-th | | Abstract: | We explored a variety of brane configurations in our previous paper within the two derivative truncation of the unstable D9-brane effective theory. In this paper we extend our previous results with emphasis on the inclusion of the higher derivative corrections for the tachyon and the gauge fields computed in the boundary string field theories. We give the exact solutions to BPS brane configurations studied in our previous paper and find remarkable exact agreements of their energies and RR-charges with the expected results. We further find a few more solutions that we could not construct in the two derivative truncations, such as a (F,D6) bound state ending on a D8-brane whose existence turns out to be due to a higher derivative effect and also the dielectric brane of Emparan and Myers as a nonsupersymmetric example. These are also in exact agreements with the results obtained in the effective theory of supersymmetric D-branes. | | Source: | arXiv, hep-th/0102174 | | Services: | Forum | Review | PDF | Favorites | |
