Optical Potential Approach to $K^{+}d$ Scattering at Low Energies

We study the $K^{+}d$ scattering at low energies using the optical potential. Our optical potential consists of the first-order and second-order terms. The total, integrated elastic and elastic differential cross sections at incident kaon momenta below 800 MeV/c are calculated using our optical potential. We found that our results are consistent with the Faddeev calculation as well as the data and especially the second-order optical potential is essential to reproduce them at low energies. We also discuss the multiple scattering effects in this process.

Photoabsorption on a Nucleon in the D_{13} Resonance Energy Region

We present a simple model for the $γN \to ππN$ reaction which reproduces the cross sections of the $π^+ π^- p, π^+ π^- n, π^+ π^0 n$ and $π^- π^0 p$ channels over the range of the energies 0.41-0.85 GeV. We use the dynamical model for the resonances, Δ(1232), N^*(1520) and ρ-meson. The total photoabsorption off a nucleon is also discussed.
