Query: The Skyrme Model piNN Form Factor and the Sea Quark Distribution of the
  Nucleon   We calculate the sea quark distribution of the nucleon in a meson cloud
model. The novel feature of our calculation is the implementation of a special
piNN form factor recently obtained by Holzwarth and Machleidt. This form factor
is hard for small and soft for large momentum transfers. We show that this
feature leads to a substantial improvement.
