We study the Kp → Y K Kπ reactions with K = K0 , K − and Y = Σ 0 , Σ + , Λ, in the region of K Kπ invariant masses of 1200 − 1550 MeV. The strong coupling of the f 1 (1285) resonance to K * K makes the mechanism based on K * exchange very efficient to produce this resonance observed in the K Kπ 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 f 1 (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 "f 1 (1420)" resonance.

We study the $${\bar{K}} p \rightarrow Y K{\bar{K}} \pi $$ K ¯ p → Y K K ¯ π reactions with $${\bar{K}} = {\bar{K}}^0, K^-$$ K ¯ = K ¯ 0 , K - and $$Y=\Sigma ^0, \Sigma ^+, \Lambda $$ Y = Σ 0 , Σ + , Λ , in the region of $$K{\bar{K}} \pi $$ K K ¯ π invariant masses of $$1200-1550$$ 1200 - 1550 MeV. The strong coupling of the $$f_1(1285)$$ f 1 ( 1285 ) resonance to $$K^* {\bar{K}}$$ K ∗ K ¯ makes the mechanism based on $$K^*$$ K ∗ exchange very efficient to produce this resonance observed in the $$K{\bar{K}} \pi $$ K K ¯ π invariant mass distribution. In addition, in all these reactions one observes an associated peak at 1420 MeV which comes from the $$K^* {\bar{K}}$$ K ∗ K ¯ decay mode of the $$f_1(1285)$$ f 1 ( 1285 ) when the $$K^*$$ K ∗ is placed on shell at higher invariant masses. We call the attention to the possibility that the peaks observed in other reactions where the “$$f_1(1420)$$ f 1 ( 1420 ) ” is observed have a similar origin.
