Description
Flavour singlet contributions to the nucleon spin are elusive due to
the fact that they cannot be determined directly in experiment but
require extrapolations to the small x region. Direct calculations of
these contributions are possible using Lattice QCD, however, they pose
a significant computational challenge due to the presence of
disconnected quark line diagrams. I report on recent progress in
determining these sea quark contributions on the lattice.
