Evidence for a narrow peak in K soπ ±π +π - at 2.6 gev in {12 gev/}/{c}overlinepp interactions
Abstract
We report the evidence for a narrow charged peak (5.5 s.d.), which we suggest calling the I, in the 6-prong-V 0 topology of overlinepp interactions at 12 GeV/ c. The mass, widht and the product of cross section σ I times the branching ratio BR into the final state (K soτ±τ +τ - are found to be: M I=2.60 ± {0.01 GeV/ }/{c 2}, Γ I⩽ {0.018 GeV/ }/{c 2}, σ I·BR≈20 μbarn
