Query: Vertex operators for the plane wave pure spinor string   In this work we give an explicit construction for the vertex operators of
massless states in the pure spinor superstring in a plane wave background. The
construction is based on the observation that the full action can be divided in
two parts, where the simpler one is based on a smaller coset and closely
resembles the gauge fixed Green-Schwarz action.
