Query: Production of Theta(1540) and Xi Pentaquark States in Proton-Proton
  Interactions   The production of strange pentaquark states (e.g. Theta baryons and Xi^--
states) in hadronic interactions within a Gribov-Regge approach is explored. In
this approach the Theta^+(1540) and the Xi Pentaquark are produced by
disintegration of remnants formed by the exchange of pomerons between the two
protons. We predict the rapidity and transverse momentum distributions as well
as the 4 pi multiplicity of the Theta^+, Xi^--, Xi^-, Xi^0 and Xi^+ for sqrt{s}
= 17 GeV (SPS) and 200 GeV (RHIC). For both energies more than 10^{-3} Theta^+
and more than 10^{-5} Xi per pp event should be observed by the present
experiments.
