An I = 1 enhancement at a mass of 1550 MeV in the (Λπ) and (Σπ)-systems

An I = 1 enhancement at a mass of 1550 MeV in the (Λπ) and (Σπ)-systems

Evidence is presented for an I = 1 enhancement observed in the reactions K-p→Λ(Σ)K01K ±π∓ at 4.2 GeV c inciden momentum. The mass and width of the proposed new Y* are, respectively, (1553 ± 7) MeV) and (80 ± 30) MeV. A decay branching ratio Σπ (Σπ + Λπ) = (35 ± 12)% is also obtained. © 1978....
