Kaon contributions to the Gerasimov-Drell-Hearn integrals on the proton

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.
