Notes on the 11D pure spinor wordline vertex operators

Understand

The construction of the ghost number zero and one vertex operators for the 11D pure spinor superparticle will be revisited.

• In this sense, an alternative way of defining the ghost number one vertex operator will be given after introducing a ghost number -2 operator made out of physical operators defined on the 11D non-minimal pure spinor superspace.
• This procedure will make explicit and transparent the relation between the ghost number three and one vertex operators.
• In addition, using a non-Lorentz covariant b-ghost, ghost number zero and two vertex operators satisfying standard descent equations will be presented in full form.
