Recently a new formalism has been developed for the covariant quantization ofsuperstrings. We study properties of Dp-branes and p-branes in this newframework, focusing on two different topics: effective actions and boundarystates for Dp-branes. We present a derivation of the Wess-Zumino terms forsuper (D)p-branes using BRST symmetry. To achieve this we derive the BRSTsymmetry for superbranes, starting from the approach with/without pure spinors,and completely characterize the WZ terms as elements of the BRST cohomology. Wealso develope the boundary state description of Dp-branes by analyzing theboundary conditions for open strings in the completely covariant (i.e., withoutpure spinors) BRST formulation.Comment: 31 pp; journal version, expended discussion of D-brane pure spinor constraints in Section 2.
