"This is the second of a series of two papers where decoupling of unphysical states in the minimal pure spinor formalism is investigated. The multi-loop amplitude prescription for the minimal pure spinor superstring formulated in hep-th/0406055 involves the insertion of picture changing operators in the path integral," scientists in Sao Paulo, Brazil report.
"In the first paper it was shown that these operators are not BRST closed inside correlators. Therefore a new proof of decoupling of BRST exact states is needed. In this paper we present such a proof, which applies to arbitrary genus," wrote N. Berkovits and colleagues.
The researchers concluded: ...
