Abstract
Using an updated kaon electroproduction operator we calculate contributions``of kaon-hyperon final states to the Gerasimov-Drell-Hearn (GDH) integrals``on the proton. We also calculate the corresponding contributions to ``the forward spin polarizability gamma0 of the proton. ``By extending the operator to the finite``Q2 region we then calculate kaon contributions to the ``longitudinal-transverse polarizability``delta0. Our results show relatively small but still sizable``contributions.
