On supersymmetric Dp–Dp brane solutions
We analyze in the spirit of hep-th/0110039 the possible existence of supersymmetric Dp– D p brane systems in flat ten-dimensional Minkowski space. For p=3,4 we show that besides the solutions related by T-duality to the D2– D 2 systems found by Bak and Karch there exist other ansatz whose compatibil...

| Sumario: | We analyze in the spirit of hep-th/0110039 the possible existence of supersymmetric Dp– D p brane systems in flat ten-dimensional Minkowski space. For p=3,4 we show that besides the solutions related by T-duality to the D2– D 2 systems found by Bak and Karch there exist other ansatz whose compatibility is shown from general arguments and that preserve also eight supercharges, in particular, a D4– D 4 system with D2-branes dissolved on it and Taub–NUT charge. We carry out the explicit construction in Weyl basis of the corresponding Killing spinors and conjecture the existence of new solutions for higher-dimensional branes with some compact directions analogous to the supertube recently found. |
