Abstract

The cross sections for $K^{+} p$ interactions at a center-of-mass energy of 3 GeV (4.3 GeV/c incident momentum) have been determined for the $K^{+} p π^{+} π^{-}$ , $K^{0} p π^{+} π^{0}$ , and $K^{0} π^{+} π^{+} n$ final states. The shape of the differential cross section $\frac{d σ}{d t^{'}}$ for the quasi-two-body final state $K^{* 0} (890) + Δ^{+ +} (1236)$ is not a single exponential. Characteristics of the low-mass $K π π$ and $p π π$ enhancements are discussed.
