Abstract
Using KAON-MAID, an operator for kaon photo- and electro-production on the nucleon, 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 γ0 of the proton. By extending the operator to the finite Q2 region we then calculate kaon contributions to the generalized GDH integrals, as well as to the longitudinal-transverse polarizability δ0. Our results show relatively small but still sizable contributions.
