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.

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.
Inspire Record 156683 DOI 10.17182/hepdata.13426

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.

Transverse Momentum of Hadrons Produced in Neutrino and Anti-neutrino Interactions on an Isoscalar Target in BEBC

The Aachen-Bonn-CERN-Democritos-London-Oxford-Saclay collaboration Deden, H. ; Fritze, P. ; Grassler, H. ; et al.
Nucl.Phys.B 181 (1981) 375, 1981.
Inspire Record 153272 DOI 10.17182/hepdata.34301

The average transverse momentum squared, 〈 p ⊥ 2 〉, of hadrons is studied as a function of W 2 and of Q 2 for ν and ν interactions on an isoscalar target. An increase of 〈 p ⊥ 2 〉 with W 2 is observed for the hadrons emitted forward in the hadronic c.m.s. The p ⊥ dependence of the fragmentation function is found to factorise from the structure function at fixed W , but does not factorise at fixed Q 2 . Unlike the case of forward-going particles, the 〈 p ⊥ 2 〉 of hadrons going backward in the c.m.s. shows no strong dependence on W 2 .

POLARIZATION OF RECOIL PROTONS FROM THE REACTION GAMMA P ---> PI0 P IN THE PHOTON ENERGY RANGE 450-MEV - 800-MEV

Bratashevsky, A.S. ; Gorbenko, V.G. ; Derebchinsky, A.I. ; et al.
Nucl.Phys.B 166 (1980) 525-533, 1980.
Inspire Record 157933 DOI 10.17182/hepdata.34552

Measurement of secondary-proton polarization from the reaction γ p → π 0 p have been performed in the proton energy range 500–800 MeV at c.m. pion emission angles 100°, 120°, 140°. The experiment was carried out using an optical spark chamber telescope at the output of the magnetic spectrometer. The obtained experimental data are included in a Walker-type analysis in order to verify the parameters of the resonances P 11 (1470), D 13 (1570) and S 11 (1535). Proton polarization in the reaction γ p → π 0 p was measured for a photon energy of 450 MeV at a c.m. pion emission angle of 105° using photons linearly polarized at 45° to the reaction plane. A liquid hydrogen target in the field of a superconducting magnet was used for the separation of the P x ′ and P z ′ components of the secondary-proton polarization vector.

The production of Ks0, Λ0, and Λ¯0 has been measured in deep-inelastic muon scattering at 225 GeV; decays into two charged hadrons were detected. Momentum distributions are compared to the inclusive charged-hadron distributions measured in the same experiment. The range of virtual-photon parameters covered is 0.4<Q2<50 GeV2 and 20<ν<210 GeV.
