BRST cohomology of the sum of two pure spinors (1301.3353v1)
Published 15 Jan 2013 in hep-th, math-ph, and math.MP
Abstract: We study the zero mode cohomology of the sum of two pure spinors. The knowledge of this cohomology allows us to better understand the structure of the massless vertex operator of the Type IIB pure spinor superstring.
