AB  - We study the K¯p→YKK¯π reactions with K¯=K¯0,K− and Y=Σ0,Σ+,Λ, in the region of KK¯π invariant masses of 1200−1550 MeV. The strong coupling of the f1(1285) resonance to K∗K¯ makes the mechanism based on K∗ exchange very efficient to produce this resonance observed in the KK¯π invariant mass distribution. In addition, in all the reactions one observes an associated peak at 1420 MeV which comes from the K∗K¯ decay mode of the f1(1285) when the K∗ is placed off shell at higher invariant masses. We claim this to be the reason for the peak of the K∗K¯ distribution seen in the experiments which has been associated to the "f1(1420)" resonance.
