Abstract
Physical states of the superstring can be described in light-cone gauge by acting with transverse bosonic α j− n and fermionic \( {\overline{q}}_{- n}^{\dot{a}} \) operators on an SO(8)-covariant superfield where j, \( \overset{\cdot }{a} \) = 1 to 8. In the pure spinor formalism, these states are described in an SO(9,1)-covariant manner by the cohomology of the BRST charge \( Q=\frac{1}{2\pi i}{\displaystyle \oint {\lambda}^a{d}_a} \) . In this paper, a similarity transformation is found which simplifies the form of Q and maps the light-cone description of the superstring vertices into DDF-like operators in the cohomology of Q.
