Chandia, O.Vallilo, B.C.2021-05-272021-05-272021-03Journal of High Energy Physics, Volume 2021, Issue 3, March 2021, Article number 16510298479http://repositorio.unab.cl/xmlui/handle/ria/18958Indexación ScopusThe 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).enSpinorTwistorsSuperstringConformal Field Models in String TheorySuperstrings and Heterotic StringsRelating the b ghost and the vertex operators of the pure spinor superstringArtículo10.1007/JHEP03(2021)165
