As was done for the D = 10 b-ghost, we will show that the D = 11 b-ghost can be simplified by introducing an SO(10, 1) fermionic vector Σ ¯ i constructed out of the fermionic spinor Dα and pure spinor variables. This simplified version will be shown to satisfy (Q, b) = T and (b, b) = BRST - trivial.engBRST QuantizationM-TheorySupergravity ModelsArtigo10.1007/JHEP07(2017)115Acesso aberto2-s2.0-850267668622-s2.0-85026766862.pdf
