A model for the reactions Kp → Qp is given assuming dominance of pomeron and ω, f exchanges. The coupling of the pomeron is taken in accord with s-channel helicity conservation (SCHC) and both real and imaginary parts of the SCH amplitudes for ω and f exchange have a t-structure in accord with amplitude analyses. The model was fitted to the 8.2 GeV/c K−p and 7–9 GeV/c K+p data and is seen to describe satisfactory the dσ/dt and (dσ/dt) ϱij distributions. A cross-over is predicted at ‖t′‖ = 0.18±0.03 which is consistent with experimental data. The energy dependence of the cross section predicted for 4 < Plab ⩽ 14 GeV/c is in good agreement with experimental data K+ and K0. The model predictions concerning s- and t-channel helicity conservation are in good agreement with current experimental data while the model predicts that for beam momenta higher than 30 GeV/c, SCHC should be apparent in all the reactions K± → Q±p, K0p → Q0p andK0p → →Q0p.
