Measurement of the x0 cross-sections in pi- p interactions at 1.6 gev/c (x0 ---> neutrals)/(x0 ---> total)

Basile, M. ; Bollini, D. ; Dalpiaz, P. ; et al.

The reactions π−p→ n+(X0→total) and π−p→ n+(X0→neutrals) have been studied at 1.6 GeV/c with the Bologna-CERN neutron missing-mass spectrometer. Both reactions have been detected without the use of visual techniques. The results are: σ(X0→total)=(108±14) μb and σ(X0→neutrals)=(20.0±3.5) μb, giving a branching ratio Γ(X0→neutrals)/Γ(X0→total)=(18.5±2.2)%. The branching ratio for other possible, so far undetected, neutral decay modes of the X0 turns out to be (2.4±1.9)%.

Observation of Resonance in the $K^{0}_{1}K^{0}_{1}$ System

Beusch, W. ; Fischer, W.E. ; Gobbi, B. ; et al.
Phys.Lett.B 25 (1967) 357-361, 1967.
Inspire Record 52538 DOI 10.17182/hepdata.29450

We have analyzed 2560 events in the final-state K O 1 K O 1 n produced in π − p interactions at 5, 7 and 12 GeV/ c . We observe the S ∗ (1070), f O and A 2 decaying into K O 1 K O 1 . Resonance parameters, cross sections, and branching ratios are given.
