Q1 Production by Hypercharge Exchange in $\pi^- p$ Interactions at 3.95-{GeV}/$c$

The CERN-College de France-Madrid-Stockholm collaboration Rodeback, S. ; Sjogren, I. ; Holmgren, S.O. ; et al.
Z.Phys.C 9 (1981) 9, 1981.

Q-meson production is studied in the hypercharge exchange reaction π-p → (Kππ)Λ at 3.95 GeV/c by selecting events witht(π- →Kππ)>1.2GeV2. An enhancement with a mass of 1294±10 MeV and a width of 66±15 MeV is observed in the (Kππ) mass distribution. A spin-parity analysis of the (Kππ) decay Dalitz plot shows the enhancement to be in theJP=1+S(Kϱ) wave and is therefore attributed toQ1-meson production. No evidence is found for the decayQ1→K0ω but limited statistics allow only placing an upper limit of 30% for the decay ratioKω/Kϱ0. TheQ1 production cross section fort(π- →Kππ)>1.2GeV2 is 8±1.3 μb. No evidence is found for the process π-p→Q2Λ withQ2→K*π for which the partial wave analysis gives an upper cross section limit of 2.5 μb at the 95% confidence level.

Results on kaon, pion, and proton production in muon-proton scattering are presented for 1<Q2<80 GeV2 with an average Bjorken x of 0.033. The measured particle fractions for z>0.2(z=Phadν) are fπ=0.764±0.028, fK=0.187±0.042, and fp=0.049±0.013. The K±π± ratios as a function of z and pT2 are presented: The ratios increase with z, and with pT2 for z<0.3.

THE C (ALPHA, X) C-11 CROSS-SECTIONS AT 1.59-GEV AND 4.19-GEV

Geaga, J.V. ; Gazzaly, M.M. ; Igo, G.J. ; et al.
Nucl.Phys.A 386 (1982) 589-598, 1982.
Inspire Record 183652 DOI 10.17182/hepdata.37081

The absolute cross sections for the production of 11 C by 1.59 GeV and 4.19 GeV α-particles incident on natural carbon have been measured to be 46.4 ± 1.3 mb and 42.5 ± 1.1 mb respectively. These results, together with data reported at other energies, indicate that the C(α, X) 11 C cross section becomes approximately constant at a value of about 43 mb for energies above 3 GeV (750 MeV/n). A similar energy dependence is exhibited by the C(p, X) 11 C reaction whose cross section has been measured previously over an extensive energy range. The C(α, X) 11 C cross sections are found to be in good agreement with predictions of a semi-empirical model developed to describe nuclear fragmentation.
