Query: Heavy quark mass expansion of vector and tensor currents and intrinsic
  charm in nucleon form factors   The framework of the expansion by subgraphs is used to compute asymptotic
expansions for the vector and the tensor currents in the limit of large quark
masses. We use the results to obtain an estimate for the influence of heavy
quarks on the nucleon electromagnetic and tensor form factors.
