Brane - Antibrane as a Defect of Tachyon Condensation | Koji Hashimoto

27 Sep 2002 | Journal: | JHEP 0212 (2002) 064 | Subject: | hep-th | Abstract: | In a tachyon effective field theory of a non-BPS brane, we construct a classical solution representing a parallel brane-antibrane. The solution is made of a kink and an antikink placed at antipodal points of S^1. Estimation of the brane energy suggests an excitation of a string connecting the two branes, even though the theory is Abelian. We performed fluctuation analysis around the obtained solution, and find the structure of the supersymmetry breaking by the co-existence of the brane and the antibrane. We discuss possible processes of the pair-annihilation of the brane defect. | Source: | arXiv, hep-th/0209232 | Services: | Forum | Review | PDF | Favorites |
