A study of K + p interactions at 4.6 GeV/ c leading to single-pion production is presented. Cross sections for the final states KΔ, K ∗ (891)p, K ∗ (1420)p are given. Comparison of the results of this study with published K − p and K − n data at the same momentum indicates that corresponding K − cross sections are significantly smaller, but other features such as momentum transfer distributions and density matrix elements are very similar.

We present results of measurements on photoproduction of ρ mesons. Analysis of 106 measured ρ events in a four-dimensional data matrix dσ(A, m, p, t⊥)dΩdm with dimensions 14×20×10×20 yields precise information on nuclear density distributions for ρ production. We obtain for the Woods-Saxon radii R(A)=(1.12±0.02)A13 and, using the vector dominance model, σρN=26.7±2.0 mb and γρ24π=0.57±0.10.
