Channel cross sections and two-body reactions in K−p interactions at 32 GeV/c

We present a systematic investigation of channel cross sections in K−p interactions at 32 GeV/c. The energy dependence of these cross sections is discussed. We also investigate a few non-diffractive two-body reactions. The total cross sections of the two reactions K−p→K∗−(890)p and K−p→K∗−(1420)p have a markedly different energy behaviour. There is clear evidence for the reaction K−p→K∗0(890) N0(1688); its differnttial cross section exhibits a sharp forward slope of 24 ± 3 GeV−2.
