Description
11D supergravity has been conjectured to be the low-energy limit of a fundamental theory, also known as M-Theory, which would contain non-perturbative information of string theory. In this talk, I will discuss the so-called 11D pure spinor superparticle whose quantization describes 11D supergravity in its antifield formulation. Since scattering amplitudes require the introduction of vertex operators carrying different ghost numbers, I will explain how such operators are constructed and the obstacle found when trying to define a ghost number zero operator, as well as the consequence of this issue on the pure spinor description of M-Theory.
