D-branes in a plane wave from covariant open strings
D-branes in a plane wave from covariant open strings
We derive boundary conditions for the covariant open string corresponding to D-branes in an Hpp-wave by requiring kappa-symmetry of its bulk action. Both half-supersymmetric and quarter-supersymmetric branes are seen to arise in this way, and the analysis furthermore agrees fully with the existing probe brane and supergravity computations. We elaborate …
