Abstract

We review the solution of the boundary CFTs that describe the symmetric branes in the Nappi‐Witten gravitational wave, namely D2 and S 1 branes. The D2 branes are the twisted branes of the model while the S 1 branes are the Cardy branes. We present in both cases the bulk‐boundary couplings and the boundary three‐point couplings and discuss the relation with branes in AdS~3~ and in S^3^. We also discuss the analogy between the open string couplings in the H~4~ model and the couplings for magnetized and intersecting branes.
