A Study of the Reactions $K^- p \to \Lambda \pi^0$, $\Lambda \eta$, $\Lambda \eta^\prime$ at 8.25-{GeV}/$c$ Incident $K^-$ Momentum

Differential cross sections and polarizations are presented for the reactions K − p → Λπ 0 , Λη , Λη ′ at 8.25 GeV/ c incident K − momentum. The data, which come from a high statistics experiment in the CERN 2 m bubble chamber, are compared with previous experimental results on the same reactions and with current theoretical ideas.

Observation of a Xi* (2370) Produced in 8.25-{GeV}/$c K^- p$ Interactions

The Birmingham-CERN-Glasgow-Michigan State-Paris collaboration Amirzadeh, J. ; Baubillier, M. ; Bloodworth, I.J. ; et al.
Phys.Lett.B 90 (1980) 324-326, 1980.
Inspire Record 143786 DOI 10.17182/hepdata.27255

We observe production of a Ξ * (2370) in the reactions K − p→ [YK¯π] K, [YK¯π] Kπ and [ΩK] (K or Kπ) at 8.25 GeV/ c in a high statistics bubble chamber experiment. The mass and width are determined to be 2373 ± 8 MeV and 80 ± 25 MeV, respectively. The I = 1/2 assignment is strongly favoured.

Evidence for the b pi decay mode of the omega (1670)

The Birmingham-CERN-Glasgow-Michigan State-Paris collaboration Baubillier, M. ; Bloodworth, I.J. ; Bossen, G.J. ; et al.
Phys.Lett.B 89 (1979) 131-135, 1979.

Backward production of ω (1670) is observed in the reactions K − p→ φ + φ − ω 0 Λ 0 and K − p→ φ + φ − φ 0 φ 0 for | U ' Λ |<1.0 GeV 2 . The cross section for the ω (1670) → φ + φ − ω 0 decay mode is 1.90±0.35 μ b for 8.25 GeV/ c incident K − . Evidence is presented for the importance of the sequential decay, ω (1670) → B φ → ωφφ with a branching ratio ω (1670) → B φ /all ω (1670) → ωφφ =1.0± 0.25 0.00 .
