4 Apr 2003 | | Journal: | Phys.Rev. D68 (2003) 066010 | | Subject: | hep-th | | Abstract: | Some of the recent important developments in understanding string/ gauge dualities are based on the idea of highly symmetric motion of ``string solitons’’ in $AdS_5 imes S^5$ geometry originally suggested by Gubser, Klebanov and Polyakov. In this paper we study symmetric motion of certain string configurations in so called Pilch-Warner geometry. The two-form field $A_2$ breaks down the supersymmetry to $mathcal{N}=1$ but for the string configurations considered in this paper the classical values of the energy and the spin are the same as for string in $AdS imes S^5$. Although trivial at classical level, the presence of NS-NS antisymmetric field couples the fluctuation modes that indicates changes in the quantum corrections to the energy spectrum. We compare our results with those obtained in the case of pp-wave limit in hep-th/0206045. | | Source: | arXiv, hep-th/0304035 | | Services: | Forum | Review | PDF | Favorites | |
