Book excerpt: Recent results of strange and strangeonium mesons are presented. The data come from a high sensitivity study (4.1 ev/nb) of K−p interactions at 11 GeV/c using the LASS spectrometer at SLAC. The complete leading orbitally-excited K* series up through J/sup P/ = 5− and a substantial number of the expected underlying states are observed decaying into K−.pi., anti K3°.pi.pi.−, and K eta final states, and new measurements are made of their masses, widths, and branching ratios. Production of strangeonium states via hypercharge exchange is observed into K3°K3°, K−K+, and K3°K/sup + -/.pi./sup - +/ final states. The leading orbitally-excited phi series through J/sup P/ = 3− is clearly seen and evidence is presented for additional high spin structure in the 2.2 GeV/c2 region. No f2(1720) is observed. The K3°K/sup + -/.pi./sup - +/ spectrum is dominated by 1/sup +/(K* anti K + anti K* K) production in the region below 1.6 GeV/c2. These results are compared with data on the same systems produced by different production mechanisms. 12 refs., 28 figs.
