Weak exchange degeneration and polarization in binary reactions π-p → K0Λ and π-p → Dsup(-)Λsub(c)sup(+)

Reactions of π-p → K deg Λ and π-p → Dsup(-)Λsub(c)sup(+) with s anti s - and c anti c - pair production are discussed. Hypothesis of weak exchange degeneration for K*, K** and D*, D** Regge trajectories is formulated. It is shown that the hypothesis turn out to be fruitful in determination of large values of asymmetries in binary reaction with strange exchanges. The hypothesis agrees in general with the amplitude analysis for π-p → Kdeg Λ reaction
