Description
In the pure spinor formulation of the superstring, in addition to the spacetime bosons and fermions the string worldsheet theory includes a ghost sector described by pure spinor fields. I will discuss the existence of a hidden action of an affine E6 Lie algebra on this sector, which arises from enhancement of SO(10) spacetime rotations together with a U(1) ghost symmetry, and whose representations encode the ghost spectrum.
