The reaction p p → K ∗ K does not exhibit any s -channel resonance effect between 1 and 2.5 GeV/ c . On the contrary, the data on p p → K ∗∓ K ± are compatible with an exchange mechanism in the t - and u -channels above 1.5 GeV/ c . Strong similarities are found with p p → K − K + and K ∗− K ∗+ . The polarisation of K ∗± is given. The reaction p p → K ∗0 K 0 vanishes above 1.5 GeV/ c

We present the results of a formation experiment for the reactions K±p→Σ±π± in the c.m.s. energy between 2200 and 2436 MeV with a total statistics of 10 ev/μb. A partial-wave analysis including these new data gives evidence for the existence of three resonances in theD15,G19 andH09 states and confirms the existence of anF05 state.

We present the results of a formation experiment for the reaction K − p → Λπ 0 in the cms energy between 2200 and 2436 MeV with a total statistics of 10 eV/μb. A partial-wave analysis including these new data gives evidence for the existence of three resonances in the P 3 , D 5 and G 9 (or H 11 ) states in this mass region.

The differential cross section for the reaction π − p→n π ° has been measured with high statistics at six incident beam momenta between 1.0 and 2.4 GeV/ c . The results are compared with predictions of recent phase shift analyses and forward dispersion relations.
