K ∗ (890) production in 10 GeV/c K − p interactions and comparison with absorption and Regge pole models

K ∗ and K ∗ (1420) resonances are observed in 10 GeV/ c K − p interactions. Masses, widths and cross sections are determined. Decay angular distributions and differential cross sections of K ∗ (890) production are compared with the absorption model and Regge pole model. While at lower energies the a...

Description
Summary:K ∗ and K ∗ (1420) resonances are observed in 10 GeV/ c K − p interactions. Masses, widths and cross sections are determined. Decay angular distributions and differential cross sections of K ∗ (890) production are compared with the absorption model and Regge pole model. While at lower energies the absorption model predictions are in reasonable agreement with experiment, serious disagreement is observed at 10 GeV/ c. Regge pole calculations including exchange of P, P′. π. ϱ. ω and A 2 trajectories can fit the data but do not explain why π exchange dominates K ∗0(890) production while ω exchange dominates K ∗−(890) production.
