Abstract

A crossover is observed in the differential cross sections for the inelastic processes $K^{0} p \to Q^{0} p$ and ${\bar{K}}^{0} p \to {\bar{Q}}^{0} p$ , from ${K_{L}}^{0} p$ data in the momentum range from 4 to 12 GeV/c. This phenomenon is evidence that Regge, in addition to Pomeranchukon, exchanges contribute to $Q$ -meson production.
