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 AdS3×S3 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.
