    A superfield realization of the integrated vertex operator in an AdS 5 × S 5 background
    (Springer Verlag, 2017-10) Chandia, O.; Vallilo, B.C.
    The integrated massless vertex operator in an AdS 5 × S 5 background in the pure spinor formalism is constructed in terms of superfields.

    Relating the b ghost and the vertex operators of the pure spinor superstring
    (Springer Science and Business Media Deutschland GmbH, 2021-03) Chandia, O.; Vallilo, B.C.
    The OPE between the composite b ghost and the unintegrated vertex operator for massless states of the pure spinor superstring is computed and shown to reproduce the structure of the bosonic string result. The double pole vanishes in the Lorenz gauge and the single pole is shown to be equal to the corresponding integrated vertex operator. © 2021, The Author(s).

    Vertex operators for the plane wave pure spinor string
    (Springer Verlag, 2018-10) Chandia, O.; Vallilo, B.C.
    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. © 2018, The Author(s).
