D-brane solutions from new isometries of pp-waves

We use recently proposed translations isometries of pp-waves to construct D4- and D3-brane solutions, using T-duality transformations, in exactly solvable pp-wave background originating from AdS(3) X S-3 geometry. A unique property of the new brane solutions is the breaking of SO(10 - p - 1) symmetry in the transverse direction of the branes due to the presence of constant NS-NS and R-R background fluxes. We verify that our 'localized' solutions satisfy the field equations and explicitly present the corresponding Killing spinors. We also show the connection of our results to certain M5-branes in pp-wave geometry. (C) 2002 Elsevier Science B.V. All rights reserved.
