Supersymmetric Branes in PP Wave Background
نویسنده
چکیده
We consider the matrix model associated with pp-wave background and construct supersymmetric branes. In addition to the spherical membrane preserving 16 supersymmetries, one may construct rotating elliptic membranes preserving 8 supersymmetries. The other branch describes rotating 1/8 BPS hyperbolic branes in general. When the angular momentum vanishes, the hyperbolic brane becomes 1/4 BPS preserving 8 real supersymmetries. It may have the shape of AdS2 or dS2 embedded in the flat three space. We study the spectrum of the worldvolume fields on the hyperbolic branes and show that there are no massless degrees. We also compute the spectrum of the 0-2 strings.

Branes in AdS and pp-wave spacetimes
We find half supersymmetric AdS-embeddings in AdS5 × S5 corresponding to all quarter BPS orthogonal intersections of D3-branes with Dp-branes. A particular case is the Karch-Randall embedding AdS4 × S2. We explicitly prove that these embeddings are supersymmetric by showing that the kappa symmetry projections are compatible with half of the target space Killing spinors and argue that all these ...
متن کاملM 5 - branes with 3 / 8 supersymmetry in pp - wave background ∗
We construct M5-branes with 3/4 supersymmetry and find that they preserve exactly half of the background pp-wave supersymmetries. We explicitly write down the standard as well as supernumerary Killing spinors and find that their respective numbers are also half of those for the pp-wave background. This is line with the recent work of Dabholkar et.al. which shows that half supersymmetric D-brane...
متن کاملAn example of localized D-branes solution on PP-wave backgrounds
In this note we provide an explicit example of type IIB supersymmetric D3-branes solution on a pp-wave like background, consisting in the product of an eight-dimensional pp-wave times a two-dimensional flat space. An interesting property of our solution is the fully localization of the D3-branes (i.e. the solution depends on all the transverse coordinates). Then we show the generalization to ot...
متن کاملDirichlet Branes of the Covariant Open Supermembrane on a PP-wave Background
We discuss an open supermembrane theory on the maximally supersymmetric pp-wave background in eleven dimensions. The boundary surfaces of an open supermembrane are studied by using the covariant supermembrane theory. In particular, we find the configurations of M5branes and 9-branes preserving a half of supersymmetries at the origin.
