Abstract We present final results on the inclusive production of the $$\bar K^{*0} (890)$$ ,K *−(890),K *0(890),K *−(890),K *−(1420), and $$\bar K^{*0} (1420)$$ resonances inK − p interactions at 32 GeV/c. Total cross sections and invariantx-distributions are determined. Inclusive cross sections of $$\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)$$ amount to ≃4 mb each, of $$\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (1420)$$ to ≃1 mb and ofK *0(890) to ≃0.8 mb. These values are in agreement with additive quark model predictions. All strangenessS=−1 resonances are predominantly produced in the forward hemisphere, the tensor mesons being more peripherally produced than the vector ones. The $$\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)$$ density matrix elements andt-distributions are obtained. The unnatural spin-parity exchange contribution to inclusive $$\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)$$ production amounts to ≳60% at |t|〈0.4 GeV2 and decreases with increasing |t|. Whenever relevant, a comparison is also made with available data at other energies.
