K Exp - p Interactions at 11 GeV/C: New Results on Strange Meson Systems

摘要

The status of our programmatic study of states containing a strange quark is briefly reviewed. An 11 GeV/c K exp - p experiment run on the LASS spectrometer at SLAC is discussed and preliminary results presented for several inelastic channels based on approximately one half of the available data sample. In addition, new results utilizing the full statistics of the experiment are presented for the elastic K exp - pi exp + channel from the K exp - pi exp + n final state. The well established leading K*(890), K*(1435), and K*(1780) resonances are observed, and clear evidence is presented for a new J/sup p/ = 4 exp + resonance at approx. 2070 MeV. Preliminary results from an energy independent partial wave analysis of these data are presented which display unambiguous evidence for resonant structure in the non-leading 0 exp + and 1 exp - waves.
