Query: Topological M Theory from Pure Spinor Formalism   We construct multiloop superparticle amplitudes in 11d using the pure spinor
formalism. We explain how this construction reduces to the superparticle limit
of the multiloop pure spinor superstring amplitudes prescription. We then argue
that this construction points to some evidence for the existence of a
topological M theory based on a relation between the ghost number of the
full-fledged supersymmetric critical models and the dimension of the spacetime
for topological models. In particular, we show that the extensions at higher
orders of the previous results for the tree and one-loop level expansion for
the superparticle in 11 dimensions is related to a topological model in 7
dimensions.
