pp Interactions at 303 GeV/c: Inclusive Studies of Gamma, $K^0_S$, and $\Lambda^0$ Production.

Dao, F.T. ; Gordon, D. ; Lach, J. ; et al.
Phys.Rev.Lett. 30 (1973) 1151-1154, 1973.
Inspire Record 81780 DOI 10.17182/hepdata.21419

From analysis of V0 events observed in an exposure of the National Accelerator Laboratory 30-in. bubble chamber to 303−GeVc protons, we obtain these results: (1) 〈nπ0〉 rises approximately linearly with n-, implying strong coupling of neutral and charged pions, while 〈nKS0〉 is less coupled to n; (2) γ, KS0, and Λ0 production cross sections are approaching a scaling limit by 303 GeVc; (3) within the limited statistics, dσdy is flat in the central region for KS0 and low-multiplicity γ events.

Structure Within the R(1675) Boson and Possible Structure within the A_2(1290)

The CERN Missing Mass Spect. collaboration Levrat, B. ; Tolstrup, C.A. ; Nef, C. ;
Phys.Lett. 22 (1966) 714-718, 1966.
Inspire Record 50977 DOI 10.17182/hepdata.29839

Three narrow peaks with masses 1632 ± 15, 1700 ± 15 and 1748 ± 15, reffered to as R 1 , R 2 and R 3 , have been observed in missing-mass spectrometer runs at incident pion momenta of 7 and 12 GeV/ c and a mass-resolution of ± 15 MeV. One-peak hypothesis gives a confidence level P ( χ 2 )=0.8%; the three-peak one gives P ( χ 2 )=60%. Statistical significance for R 1 , R 2 and R 3 is, respectively, 3.8, 6.6 and 6.1 standard deviations from the highest background line. R 1 and R 2 decay into one and three, while the R 3 decays mainly into three charged particles. Their physical widths are compatible with zero, with upper limits of the order of Γ ⩽30 MeV.
