1/2-BPS D-branes from covariant open superstringin AdS(4) X CP3 background

Abstract

We consider the open superstring action in the AdS(4) x CP3 background and investigate the suitable boundary conditions for the open superstring describing the 1/2-BPS D-branes by imposing the kappa-symmetry of the action. This results in the classi fi cation of 1/2-BPS D-branes from covariant open superstring. It is shown that the 1/2-BPS D-brane con fi gurations are restricted considerably by the Kahler structure on CP3. We just consider D-branes without worldvolume fluxes.
