We present experimental results and a partial-wave analysis of the low-mass ( K π) 0 systems produced in the reactions K − p → K π N at 14.3 GeV/ c . The main results concern the production mechanisms of the K ∗ (890) and K ∗ (1420) . We also extract the s-wave component of the K π system as a function of mass.
THE ERRORS QUOTED (EXCEPT FOR THE FIRST REACTION) ARE MAINLY AN ESTIMATE OF THE SYSTEMATIC UNCERTAINTIES.

Differential cross sections and density matrix elements are presented for K ∗− (890) and K ∗− (1400) produced in the reaction K − p→K O π − p at 3.95 GeV/ c . The cross sections are decomposed into contributions due to different exchange mechanisms.
