A Projection to the Pure Spinor Space    [PDF]

Sebastian Guttenberg

This article is based on a talk given at the Memorial Conference for
Maximilian Kreuzer at the ESI in Vienna and contains a compact summary of a
recent collaboration with P.A. Grassi. A non-linear projection from the space
of SO(10) Weyl spinors to the space of pure spinors is presented together with
some of its particular properties. This projection can be used to remove the
constraints from Berkovits' pure spinor superstring while introducing
additional gauge symmetries. This should allow to make transitions to
equivalent formulations which might shed light on the origin of the pure spinor
ghosts. It might also be useful in the context of path integral measures for
the pure spinor string.
