Abstract

Inclusive production cross sections have been measured for the processes p+A→Ξ0+X (A=Be, Cu, Pb) and for p+Be→Ξ¯0+X. Data were taken at angles of 0, 2, 3.5, 7.3, and 9.8 mrad between the incident 400-GeV proton beam and the outgoing hyperon beam. Production cross sections for Λ and Λ¯ production were measured at the same time. The A dependence of the Ξ0 cross sections is discussed, along with interpretations in terms of various models.

  21. The same remarks apply to any other S=2 states on the same Regge trajectory. One example would be a scalar meson with a mass of 0.8 GeV/c or lower. Such a state, which would be stable against strong decay, has not been observed.
